I have an established 75 gallon tank with live rock and no corals (they are in my other tank). In it I have 2 clownfish, a goby, 2 damsels, and the new lemon peel angel. I’ve had the lemon peel for about a week now and it has barely eaten anything. When I feed the fish he acts like the food isn’t even there. I have been feeding the fish a carnivorous and omnivorous pellet food, a veggie and seaweed pellet food, and sometimes just plain seaweed. He is looking very skinny and I am worried. PLEASE HELP
