What is your experience with Macaw cichlids?

Definitely! Please do! Would be interested to see such a big group at such a size - interesting that you are seeing different markings between them all.

At 3-4 inches you should be able to sex them quite easy, the males get a spotty pattern in the dorsal and tail fin with a black spot on the side and the females should have a black stripe down the middle of the body, no spotting in the fins and the dorsal fin should be turning a metallic blue.

I'm including ine that I think is a male (#1) my favorite, #2 I think is a female, and #3 seems to have some vertical bars...this is not all of them of course. They are so hard to photograph or even count, because they are so fast.

Missed these posts sorry

I agree 1 is male and 2 is female - males have the spot on the side females have the stripes. I can see the underlying tiger stripes in all of these so far so will be interesting to see how they colour up I'm still no wiser what the black markings mean on this species. If I ever won the lottery I think investigating Nicaraguan Cichlids would be one of my splurges haha
