Nice hybrids , not FH MUTT JUNK
Not to derail, but if this were about crossing two pure species of cichlids, it would still get dumped into the hybrid forum. A ray hybrid is the same as any other hybrid. It's not nice, or better, than any other mutt around. Reality check.
That said, I hope your rays have some pups you can enjoy.
Good questions Keepin. I wonder if the females just aren't ready yet? You've had them for just over 3 years?
