Get columbian pictus,1 yellow bullhead(not black or brown bullheads as they can be slightly evil),and 1 eclipse catfishSo my wife wants some pictus catfish how would I go about making sure I get ones that would get over 5"(I know there are 2 species one gets 4"-5" the other up to 10") I don't want to get one that a bull head or eclipse would just end up eating or is a 5" fish big enough that they wouldn't eat them?
