    I recently got a couple of breeding colonies to produce nice red hybrid tilapia. Very cool system that produces all male fish.

    Papa is O. hornorum.

    Moms are O. mossambicas.

    I always thought talipia were just food fish but must say very pretty fish you have worth keeping just for the looks

    I was wondering. Have you tried breeding those male hybrids with any oreochromis feamales and what was the outcome. I have male red hybrids and a female nile tilapia and female oreochromis's think I'll get red from them?

    These are intended for food, but I think they have potential as an aquarium fish too. The purpose of the two species is to produce all male hybrids. The hornorum us a ZZ-ZW sex combo where the males are ZZ. The mossambicas are XY-XX like people where XX is female. Cross a ZZ with a XX and all the offstring are ZX. about 95% are male and quite red.

    Your red hybrids were produced from such a cross then crossed into the niles to produce the Florida reds. It is anyones guess what crossing them back to pure hororums would give you.
