I dunno about cyprinids. Sunfish hybrids often are fertile- if not all of
them, and sometimes have both male and female hybrids. General rule is more
males. I don't know if they are ever sterile. I have spawned hybrids in a
tank, and thier young mostly look like the hybrid adults, but some look
closer to one of the orginal parent species, and a few look closer to the
other. Unfortunatly I was not able to raise enough of these up to try to
spawn them again,genetically weak? This even confuses more triple crosses.
That is when a hybrid of A and B spawns with species C and makes some really
odd looking sunfish.

I am thinking that these hybrids that do spawn, the young are genetically
weak. If the hybrid spawns back with one parent specie or the other,
supposedly many of the young will drop the hybrid traits and take one the
characteristics of the "purebred" parent.

That is my next experiment, if I have time and space. There are just too
many fish to work with, and mucking with that takes up time and energy
better spent on other things. The ones I have worked with are
pumpkinseedXgreen sunfish and warmouthXgreen sunfish.
