thats tru but but a well fed cray wont chase your fish. and the fry is usually much faster than them. i may have lost one or two but never been able to tell so nothing too terrible. and it seems like she has a big tank if she wants to add a 12 inch catfish. the mollie fry will stay on top mostly. i raise managuense fry with my crayfish and they stay low. he still dont bother them.Pazzoman;4462326; said:b care ful with crays if they can get thier claw on a fish...it's over lol
