Keeping and Breeding Tropical Fish: From Angelfish to Killies

When I was a boy and in my early teens, besides various caterpillars, silk-moths and stick insects, I also had a lot of tropical fish. In fact, I had tanks all around my bedroom. I used to breed many species of fish, including angel fish, keyhole cichlids, golden barbs and paradise fish.

Keyhole Cichlids

Some types of fish eat their eggs and so it was vitally important for me to be able to get the parents out as soon as they had laid their eggs. I used to stay up into the early hours watching for this to happen. My mother used to get annoyed and would tell me I should be asleep because I had school in the morning. I never cared about school because my insects and fish were my world and what was important to me.

It was in my early teens that I really got into keeping tropical fish and had a school friend called Roger Wiggins who used to keep tropicals too. We used to read magazines for aquarists and find out about fish farms in America and read about specialist breeders of difficult species, and we would fantasise about one day running our own tropical fish businesses. By that time I had started selling surplus fish that I had reared in the tropical fish shops in Cardiff, and sometimes I would supply them with bags of water lettuce, a floating plant I used to get so much of it covered the tops of the water in my tanks. They never used to pay me much for the fish and plants but it was a boost to my ego to be able to think I was successful at being a supplier, even if on a really small scale. The men that ran the shops knew that I knew my stuff too. It all appealed to my youthful sense of pride.

Roger and I used to order exotic aquatic plant species from mail order companies too. It was exciting seeing what the plants were actually like and to find out how well we could grow them. Often enough our efforts failed but that did not stop us. I remember being fascinated by the names we read in ads and wondering what these plants would really be like. Some like the aptly named four-leaf clover turned out to be really great and easy to grow aquatic plants but others just withered away.

I also remember going to Newport to a tropical fish shop in the Pill area of the city. Tachbook Tropicals I think it was. It was worth making this trip by train, not just for a day out, but because for some reason this shop always had fish you could not find in any of the shops in Cardiff. I remember getting an Egyptian mouthbreeder or mouthbrooder and a skunk botia from Newport.

Egyptian Mouthbrooder

The mouthbreeder was a female and I had her for years. Sadly I never managed to get a male and though she used to spawn on her own her efforts were wasted because the unfertilised eggs died and after she realised this she ate them. It was sad seeing this dedicated mother fish with a mouthful of eggs, not able to eat and expecting her eggs to hatch into tiny babies but never have any hatch out. My Auntie Elsie from London who used to often visit used to call this fish “Ugly” but I couldn’t see why. But it was a male I needed and for some reason every time I saw these mouth-breeders for sale there were never any males. There were unexplained mysteries in the tropical fish business. In Cardiff they were never on sale in either sex. I never understood why because it was an interesting fish, easy to keep and in most tropical fish books.

I remember something else that happened that involved my Auntie Elsie and a fish I had at the time. It showed me something about how human opinions can be so very wrong and how animals and plants are built to survive and repair themselves if hurt. I had an upside down catfish.

These fish are named that way because they do swim upside down. The one I had was a greedy fish and was always on the lookout for more food but one day it had a terrible accident that was to cause it to stop eating. What happened was that for some reason, which I cannot remember, the fish was very alarmed and dived down fast towards the bottom of the tank. In its speed it failed to watch out for a jagged rock and cut its belly open. It was really badly hurt because I could see its innards that spilled out through the cut it sustained. My Auntie saw me upset and asked what was wrong and I told her what happened. She took one look at the catfish and said I should do the right thing, and put it out of its misery, because there was no way it would survive. I didn’t want to kill my fish. I hoped so badly it would get better. I decided to give it a chance, though I could clearly see that the odds were against it pulling through. My catfish retreated to a corner of the tank, stopped eating and swimming about and just stayed there, hanging almost motionless in the corner. The days rolled onward and the fish didn’t die. It didn’t resume its normal lifestyle of swimming around and looking for food but it didn’t die. What happened was a miracle. The guts of the fish were very gradually being pulled back inside its belly, and the skin was closing over. Eventually, after about a week, wound had closed and all was left was a scar. The catfish gradually started to take an interest in life again and moved around in the tank, and most importantly, began eating again. Within a few weeks, it was back to normal and even the scar on its belly vanished. I was so glad I had not listened to Auntie Elsie, and that I had given my fish a chance.

But getting back to my friend Roger and our shared hobby; we had an ongoing mystery. You see, we never saw any killifish for sale, though we read about these unusual fish in books and magazines. Because of their habits of laying eggs that need to be kept semi-dry to replicate the conditions in the wild where ponds dry up, we assumed these species really were so difficult that this is why they were not available in South Wales. These were fish it was probably too hard to keep and breed. This is what we thought was the reason why people do not keep killies. Many years later I was to find out that this assumption was wrong. It was possible to order killifish by post, as eggs or adult fish. Some types were very hard to keep but others were easy. I became a member of the British KIllifish Association in the 1990s. This meant I received the society’s monthly journal and could read the ads and respond. I could order eggs from other members. The killifish eggs were in peat and used to be contained in small plastic containers or in plastic sachets. They could be sent through the mail this way. The excitement came from hatching the tiny fish out and seeing if you could rear them successfully. Some types like the Nothobranchius species were exceedingly colourful with the males having red tails and bright blue bodies. I was successful in breeding and rearing quite a few species, including some of the larger bottom-spawning aphyosemion species, such as the Blue Gularis.

I was proud of my success with these fish. I sold a lot to a local fish shop where I knew the owner Neil. Sadly though he was to tell me that many of them died. I never sold him any more after that. These fish I found easy to keep could not survive in a tank in a shop. perhaps they did need specialist care after all?

I have another fish story I would like to share. I had a pair of some type of mouthbrooding cichlid. I say “some type,” because they were not identified when I bought them and I never did find out what they were. There are a lot of African mouthbreeder cichlids and these were mostly a yellowish colour and it was clear which the male was because he was a lot bigger and he used to dig pits in the gravel, which is something male fish do to attract mates. I also could see that the other was the female because the fish used to breed but sadly, for some reason, I never discovered, they always lost their eggs which failed to hatch. Nevertheless, this pair of fish seemed OK in my community tank and never bothered other fish I had. I mention this because many cichlids are known for being aggressive and cannot be kept with other species. But all of this, I have just told you, is not what this story is about. What I really want to share is what happened when the female fish died. I cannot remember what was wrong with her but I can vividly remember what happened to the male. It was as if he lost his will to live, like a brokenhearted human it seemed he no longer had any reason to be alive without his mate. Now, what you probably don’t know is that there are many fish that are monogamous and faithful to their mates. There are fish that mate for life and are far more loyal to their partners than many married humans can be. Anyway, what happened with my male cichlid, and how I could see he was grieving badly, was that he stopped eating, stopped showing an interest in swimming around the tank, stopped digging in the gravel, and like the upside down catfish I have already told you about, he went into a corner of the tank and just lay on the gravel. After seeing him behave this way for several days I thought he was pining away and would die, but I was wrong. Something amazing happened that showed that fish can respond to humans and that one species can communicate with another.

My friend Sioned used to call at my house on a regular basis. One day she called round and had gone in the kitchen for something, which was where the tank was I had my cichlid in. She asked me what was the matter with my fish. I told her that he was very sad and grieving because his wife had died. I said I thought he would die too because he wasn’t eating. Sioned was horrified and said she was going to see if she could help save him. She started gently tapping on the side of the tank and talking to the fish through the glass. My friend repeated this every time she visited which was every day that week. My heart-broken male cichlid began to respond. He left lying in the corner and would come over to see Sioned through the glass pane. Eventually after a few days he started eating again, and swimming about. He even began digging in the gravel. probably in the hope that his mate would somehow return, or maybe to attract a new mate. This never happened, of course, and I was unable to get any more of this type of fish, though I looked in the local tropical fish shops. As a result of my friend Sioned spending time trying to talk to my male cichlid and succeeding, he went on to live many months more.

Kenfig Pool and Kenfig Sand Dunes

I was thinking about places in the countryside that I remember from my childhood and thought I would like to tell you about Kenfig Pool and the sand dunes there. My parents used to take me to this amazing place when I was a boy. We used to go on lots of days out, visiting the countryside. My dad had a blue Vanguard car and this is what we would go out in. Mum and Dad were always encouraging when it came to my interest in nature and they used to buy me lots of books. I had most of the Observer’s Books.

Observer's Books (Photo: Wikipedia, Fair use for illustrative purposes)

I had the Observer’s Book of British Wild Flowers, and the book on fungi and British birds, and wild animals, and freshwater fish, and even the Observer’s Book of Mosses and Liverworts. That last book was given to me when I was only five, and I know that because it has survived and is at my Dad’s house still, I think, and it is signed to me in the front for my “Fifth birthday.”

Anyway, one place we used to go which I really used to love was Kenfig. It is near Porthcawl but much wilder. There is a big lake called Kenfig Pool and miles and miles of sand dunes.

These dunes have rough paths through them and eventually you can get to a long sandy beach by the sea. It takes well over an hour, as I remember it, to get from the carpark to the beach. But the walk is the real fun of it all. There were so many wild flowers I could look out for and insects and newts and frogs and toads, lizards too.

Kenfig Pool

There were temporary pools that formed in the dunes and they had boggy bits around them with sphagnum moss and bog myrtle. I used to love the smell of marshy ground, especially if there was water mint that added its aroma if you stepped on it or brushed by it as you were walking. In these pools there were newts and water beetles and other water insects. I was always fascinated by water, by ponds, streams and rivers, and rock pools when we went to beaches. I used to wear my Wellingtons so I could investigate the watery places without getting my feet wet, though often I did get water in my boots and my Mum used to get mad at me because of this.

Part of the fascination was I never knew what I would find. I was exploring. It was like it stirred some sort of instinct to hunt for life; I was a hunter-gatherer boy. In those days, I was forever turning stones over, looking under boards and corrugated iron on waste ground, wading around in muddy ponds, seeing what I could catch in rivers and streams, and exploring the railway bank behind where we lived. Nature was my world. It meant much more to me than people and the human world and I hated school.

But getting back to Kenfig, one of the reasons I was so excited by the place was because there were rare wild flowers to be found there. I used to like looking up plants in my wild-flower books. I used to always be on the lookout for new species and hoping I would discover something really rare. Wintergreen, hound’s tongue and many types of orchids were some of the rare plants that grew at Kenfig Dunes. I used to find blue viper’s bugloss and pink centaury and also we used to look out for dewberries, a type of blackberry that grew in the dunes. We used to collect them and take them home so Mum could make pie which we used to have with custard. I used to love eating blackberry pie and custard or just stewed blackberries and custard.

Often I used to go on ahead of my family, or be lagging behind them, as we made our way over the dunes. I was always investigating some marshy ground, turning over any boulders or rubbish I found or searching in the vegetation. I remember there were some parts where you could find common lizards. They would bask on bits of discarded iron sheeting and on boards and other rubbish that littered the dunes even then….this was back in the early 1960s.

I used to try and spot great green grasshoppers too. These insects are, as their name suggests, very big, the size of locusts. They lived in some parts of the dunes and you could hear them singing but they are really difficult to find. The insects blend in so well with the vegetation and they stop singing as soon as you get anywhere near them. Most frustrating!

Often I found young toads and they seemed happy in the sandy soil. I remember thinking about natterjack toads I had read about in my books. They liked habitats like this but were very rare and didn’t live in South Wales but that didn’t stop me dreaming I would find them there.

There were lots of butterflies too. Wall butterflies, meadow browns, common blues, small coppers, small heaths and the colourful day-flying moths known as burnet moths. Many of these types of butterfly you hardly ever see in Britain today. It has always depressed me to watch wildlife vanishing. I never thought it would happen when I was younger. I mean, you don’t think about these things. You think everything will always be there somehow.

In spring though it was amazing because that is when there were most wild-flowers in bloom and the ponds were full of water. At this time too, if you happened to get there at the right time, it was possible to see thousands of adult toads making their way to Kenfig Pool. They used to use the lake to breed in and I remember seeing these amphibians all over the ground on the shores of the lake and in the water around the edges. many of them were mated pairs, in what naturalists call amplexus, where the male toad grasps the female with his arms round her and rides on her back.

I used to like the idea of how wild it felt once you got away from the road and ‘civilisation.’ It was just miles of sand dunes covered in marram grass and other plants that tolerated the sandy soil, the sky above and hardly a soul ever in sight. Most people stayed in the car-park, few ventured into the dunes and were prepared to make the long trek.

When we were getting near the beach area you could tell. There were visible signs if you knew what to look out for. The sand got more so, less covered in vegetation, and new plants appeared.  The weird and prickly sea holly and sea spurge, food-plant for the rare spurge hawk moth. It was a moth I always hoped to someday see but never did. It is funny how we can live in expectation of some dream coming true, even though it is very much against the odds. It seems easier to do this when you are younger.

In this part of Kenfig it was like a zone, a border between the dunes and the beach, a place where different plants would grow. Then there was the top of the beach proper with rotting seaweed, bladderwrack with sandhoppers underneath it. I always used to enjoy moving the weed and seeing the hundreds of little crustaceans jumping about and seeking cover. It fascinated me how they all lived under these piles of seaweed.

Sandhoppers

So Kenfig was very much a part of my childhood and early teens. I don’t know what it is like today, probably spoiled to some degree. Most of my life and growing up I bore witness to seeing places I loved in the countryside getting ruined. I am sure you know what I mean, I mean watching places get built all over, ponds drained, roads built etc etc. Reminds me of the Joni Mitchell song: “They paved paradise and put up a parking lot.” But the wild places are still there in my head, in my memories, and are very much a part of what has made me as I am.

5 cleanest lakes in the world

Clean lakes are an important water resource for many reasons. They are a great attraction for tourists, a place where many activities such as fishing, swimming and sailing can be enjoyed, and a natural environment for wildlife.  They can also be used as reservoirs.

1. Lake Annecy

Lake Annecy or Lac d’Annecy, as it is called in French, is the third largest lake in France and is located in the mountains of the Haute-Savoie region, of which Annecy is the capital. Lake Annecy is recognised as “Europe’s cleanest lake.”

Lake Annecy is a very popular with tourists who often take part in swimming diving, and other water sports.

Annecy is a wonderful place not just for sightseeing but for learning French and there is a French Language School established in the town.

2. Blue Lake (Tasman)

Blue Lake is the name given to a small lake in the Nelson Lakes National Park, which is part of the Southern Alps of New Zealand. Also known as Rotomairewhenua, it is the clearest freshwater lake in the whole world and is sacred to the Maori people. Swimming and diving are not allowed and use of this lake is strictly controlled.

It is drained by the western branch of the Sabine River and is usually reached from the Travers-Sabine Circuit.

3. Lake McKenzie

Lake McKenzie is also known as Boorangoora and is located on Fraser Island in Queensland, Australia. Its sands are white and composed of silica and the water is so pure that many freshwater species cannot live in it.

Many people visit Lake McKenzie to sunbathe on its shores and enjoy its unique beauty. Camping and picnic areas are provided as well as public toilets.

4. Crater Lake

Crater Lake in Oregon is the deepest lake in North America. It is actually a caldera lake and was formed some 7,700 years ago by the collapse of the volcano that is known today as Mount Mazama.

With no rivers going in or out of the lake, it is only filled by rain and melted snow and there is little to cause water pollution. Because of this Crater Lake has become world famous for its exceptional clarity and deep blue colour.

Crater Lake is also famous for a full-sized tree that, preserved by the coldness of the water, has been bobbing about in the waters of the lake for over a century and has now worn down to a very large stump and has affectionately become known as the “Old Man of the Lake.”

5. Arnensee

Lake Arnen (Photo: imagea.org)

The Arnensee is a lake in the Berne area of Switzerland, and is also known as Lake Arnen.  The Arnensee is used as a reservoir, but referring to the lake’s great beauty and location in the municipality of Gsteig in the Swiss mountains, it has been called the “Pearl of Saanenland.”
