Looks like they are all going to be males. Grow them up a bit and make sure to pick the best one. My advice would be to also make sure it is not overly aggressive because the male I have has never even harmed my female at all. Not sure how I got so lucky with this pair. Dan from Cichlids of the Americas has some RTM's. Knowing his fish those will turn out good. on my last $500 order he even threw in a lot of extra free fish on top of it!
