So, I have a 28 gallon JBJ Nano, all my parameters are stable and within normal range. I have 2 false perc clowns, a Leopard Wrasse and a Lubbock's Fairy Wrasse and a twin spot goby. I got my Tang about a week ago and it picks at the rocks but doesn't really eat anything else. I alternate between Hikari Mysis and Spirulina Brine Shrimp. I have tried Julian Sprung's "Sea Veggies" sheets on a clip and now I soak them and break them up and add it to the tank. I have not really seen the fish eat anything significant and it is losing color. Anyone familiar with this fish that could lend advise would be greatly appreciated!!!
