Hello, any ideas why this angelfish is not eating? I’ve had him for a few weeks, he ate at first, very slow eater but ate little bits of the floor. Now he hasn’t eaten for a several days, maybe a week. Any ideas, I’ve tried frozen mysis, plankton, angel marine mix, angel frozen mix, new life spectrum pellets, nyos algae and berry pellets. He doesn’t eat! I mix all my food with selcon and/or with the Germany amino acid concentrate liquid additive. What’s the trick here?! What am I missing! Please help, any suggestions. I have another dwarf angel who eats like a pig.
