My Male Jack Dempsey is losing his scales. Is he trying to mate with the female or what? He is about 3" long and the female is about 4" long. They are in with 4 firemouths And seem to get along fine. Never so any signs of fighting, if they do chase it's usually the firemouths that chase each other. Have had all since they were small fry. My tank is 75 gal. I also have a 15" placoustimous in there, and was wondering if I need to continue to feed every day, and if so shoud I increase food.snow.
