So I originally thought I had one male peacock cichlid and two female peacock cichlids, they're usually pretty easy to tell since the males have such bright colors and the females are a dull golden or brown color. My two females schooled together in the beginning and the male would chase them around. They both were Brown with very light stripes. Now that they've gotten used to the tank they've all separated and one of my females keeps chasing the male. When this was happening he was getting more vivid colors and his face is turning blue along with his tail and some of his body. Now he's digging a hole in the substrate and I push it back and he redigs it. I've read that males do that trying to get a female to lay eggs. I was hoping to get some opinions on what y'all think. I'm totally stumped at this point. Is this a female or has this been a male in disguise the whole time?
