I love all kinds of fish. I have gold fish, a salt water reef & a discus tank @ present. I loved the challenge that all presented. I'm not always happy with my tanks. Right now, my reef needs work. I have the discus beause I have read everywhere that they are called "The King of Fish " & very difficult to keep. I love the challenge. I was told that having 2 adult discus in a 30 gallon was impossible. Well, here I am, proof that it can be done. ( & yes, they are both beautiful & happy ) Everywhere I read said I needed @ least a 20 gallon for 1 fancy gold fish. When I read something like that, I rise to the challenge & try to beat the odds. For 5 years I had an adult fantail, black moor & comet in a 10 gallon tank. None of them hovered in the corner. The tank was the first thing to be seen as you entered our home. We received many favourable coments. I did spend alot of time keeping the gravel & filter clean as gold fish create alot of waste. I have just recently lost my black moor & comet. The fantail continues to do well. It was 5 years before I lost my first fish in this tank. I will add no more fish till the fantail is gone. It wouldn't be fair, but then, I'll start all over again. I don't have any questions. I just wrote this to tell everyone that, if you are ready to invest alot of time & effort, you can beat all odds & raise beautiful , happy & healthy fish.
