Last April I purchased several guaranteed males on line. They were juvies and were added to my 210 with a mix of haps, peacocks and Mbundu. Goal was to have an all male tank. Best intentions. Of course over the last year I have lost a few and don't know if they were among them, have not yet colored up, or are females. Two have a orangish tint to their shoulders and one is tighter striped, dark brown and lacy dorsaland tail fins. Could they still be not colored up?
