I purchased two black and white cardinals a month or so ago. I recently added a wrasse, and while I thought the royal gamma would pick the wrasse apart, they acclimated very well. Fast forward a few weeks and I notice one of my cardinal is hiding anywhere it can find, top fins chewed off. As I observe, I see the dominant one hounding the second relentlessly. Cardinal comes out to feed and looks healthy but for the hiding and battered fins.
What can I do? Should I let them work it out? Will those fins welcome disease? Death or removal?
