My dominant red zebra male has lost his status to my albino red zebra male and has taken this change hard. For last 2 weeks they coexisted perfectly - the albino (whitey bulged) assumed the Center of the tank and maui as I call him assumed the right side of the tank. I had finally got them to cease the chasing and fighting took a lot of interference on my part but they coexisted and ate together even on multiple occasions could be found treading water together chasing other fish around. But today I ve noticed a new behaviour. I’m use to seeing females or sub dominant males floating in corners face down but never face up. Any insight as I already have an idea of stress and plan to grab some more females for them both
