Been watching these new guys like a hawk since they got here. I think I can tell the sexes apart for the Devil's. It looks like I have 4 male's 1 female.
This is the one I suspect as female.
It's unpaired fins are rounded, has a different shaped forehead area. Also the males seem to be thicker along the dorsal fin area.
So if it is 4 males, I think I will wait for them to finish pealing, pick out 2 favorite male's. Rehome the other two, and hope the sole female likes one of the two.
The Texans are a different story, no clue on these guys yet, they all look the same. Maybe a bit young yet.
