what fish have not been breed successfully in captivity?

hmm ya guess I'm just very uneducated on the subject, have never breed anything on purpose.

anything you're curious about just search on mfk or google (which'll probably lead you back to mfk). i'm sure people have asked about everything and all kinds of weird crosses
