When I was growing up we always had big catfish, had several tsn and rtc an arrowana. My first tank was a crayfish that I had caught in a creek, had toads as well, but my first fish aquarium had a Brown bullhead that I had caught while fishing, I had it a little over a year and we went on vacation for a week and the lady over fed it and water quality killed it. My parents were friends with a lfs owner so we got to babysit all kinds of cool critters from gators to tortoises. I've been hooked on big catfish ever since I was a kid. The wife and I had a parrot fish for almost 13 years, he moved cross country with us and recently went to the aquarium in the sky. I now have a speckeled bullhead in a 55 gallon and my snapping turtle is in a 75. I am in process of building a 300 gallon for turtle, the 55 will be used as a sump and the catfish will be moved to the 75. Some day when I can sweet talk wife enough, I want to get a goonch cat. My daughter is getting into aquarims now, she has some crayfish that she caught and a bullfrog as well that she caught
