My koran angel has been fading over the last year. All fish in the tank are healthy. Only deaths have been my stupidity and some kamikaze jumpers. sp 1.022, 0 nitrates, minimal phosphates (working on ), temp 78-81, eats brine, mysis, and bloodworms. He eats great, is social, fins on top have not been regenerating well. I am getting back into the hobby and want to know where i went wrong with this guy and if i can fix it. Is it a illness, does he need supplement, water quality????? Any feedback is appreciated. thanx
