It has a pretty good sized pointed anal fin, a male trait. At about 3" my Fusco turned sort of red, then its face slowly began to turn blue. Full color by 4.5".

The Haps don't particularly take advantage of the caves but do dash through the gaps and crevaces. Your group of new Haps would probably appreciate more hiding spots during the acclimation period.
