Hi I posted this question under natives but didn't get much response so trying it here. Can you tell the difference in sexes with blue gill or do you just put them together and see if they pair off?

i would say if you have some experience breeding you could it is similar to cichlids but very minute

males will be more agressive
females will have a much rounder belly
some species show a small hump on the head no comparison with some cichlids

but if they are small it is really hard
thats the best i can do i am sure you will get more replies

Sexing bluegills:
Males have deeper bodies and much more color than females.
The females generally have vertical bars on them and the males develop
a deep orange breast area when they are ready to spawn. Males will
make nests in the substrate. One trick that we found was to put a line of
plants or other stuff in the tank partially blocking off about a foot of the
end of a tank. A male would then take over this end area and start nesting.
Nest making will be obvious -- the male sweeps material out of a circular
patch with his fins, particularly his tail fin.
