i have had a electric catfish for several month now and it's about 5-6 inches. so far, it's been doing fine alone in a 10g tank, but i want to keep it with my other tropical fishs in a 75g tank. i used a feeder fish for several days to test and see if the catfish would kill its tankmate, but nothing happened. today, i decided to put it in with my bgk, angel, bichir and etc. hopefully, it wont decide to kill any of them.
