Any fish you add should be longer then the rays disk is wide... from experiance.. my female retic actively hunts other fish... she has been fine however with my spiney eels. She eats 3"+ goldfish when I feed the gar, actively hunting and pouncing on them. My tanks pretty bio-diverse.
I will keep this in mind! I have several grow out tanks so even if I get stuff a little small I can grow it some before I add them together. My female doesn't hunt fish too much but my male is always looking for a quick meal. It is weird though he wound eat small pbass just the feeders I put in, knock on wood. Any experiences with severums and rays? I am going to try to pick up some geos on friday too!
