I got a discus from my local fish store a little over 3 weeks ago. He didn't eat anything while he was in quarantine for 2 weeks. He's now with in my planted tank with a orange discus but he's still not eating. Him and my orange have started spawning though... I'm worried as he is getting thin. I have tried blood worms soaked in garlic guard, Cobalt discus flakes, new era pellets, brine shrimps and mysis shrimp. Any idea? I saw a post about orange peels so I might try that. Should I leave him in the tank or should I remove him?
