Please help. This is my first fish in my new 75 gal reef tank. It has been cycling for 1 mo. I have had him for 4 days. He has a new injury to his tail from unknown cause. Only other tank mates are 2 nassairaus snails. He is not eating small pellets soaked or not soaked, or flake or chopped shrimp. His tail has a moon shaped chunch missing out of it. I think he might have gotten into the power head or who knows. I turned my 2 korilla 5 power heads off to give him a break in swimming. What can I do to get him to eat? Reefgo
