The largest fish in my sauolsi tank is about 2" long and appears to be a female - still a solid golden yellow/orange, with no hint of any colour change. Over the last couple of days this fish has been clearing a nest area under one of the rocks by spitting sand. I've seen other male mbuna do this, but never seen a female behave this way.
Do females make nests? Or just clear caves in general? Or could this be a male that hasn't started changing colour? There is a smaller fish in the tank that is just getting some blue along his dorsal fin and some banding across the top of his head, along with some changes to his body colour. He has a golden egg spot, whereas the larger fish doesn't. There are 12 juveniles in the tank, with these two being the biggest of them.
