i paranoid, i cant put anything in my tanks besides fish food...alhtough ive been dying to toss a earhtworm from the back yard to my eel. I do remember when i was yournger my uncle had a pirhana tank and he use to feed them hotdogs.
pompano, tilapia, chicken hearts, night crawlers, beetles, spiders, hornets, rats, snakes, newts, snails, mussels, crayfish, tomatoes, strawberries, bananas, ect, ect, ect. I keep nothing but huge catfish, and they need a varried diet. Funny to watch my 4" rtc eat a 9" night crawler. lol
