I got a new baby yellow slider a day ago. It's roughly the size of a quarter. I was wondering if it would be possible to introduce it to my 75g with a 10 inch electric catfish and some other fishes. The catfish is very calm and eats NOTHING but earthworms. However, it occasionally shock its tankmates, though never strongly, and only when they steal his food. The reason I want to do it now is because I want turtle to recognize fish as tankmates, not food before it grows up. It's not nippy at all yet, so would it still be risky?
