Hey guys, im worried about my lieutenant tang because he is getting really thin ( i can see his rib cage clearly now).. i have tried almost everything and he keeps getting thinner. Not sure what else to do. I feed: Formula 1 and 2 pellets. Formula 2 flakes, PE mysis, regular mysis, and emerald cubes ( which contain brine, spirulina, mysis, krill and some other alage). I also soak the food in garlic. he takes a bite, spits it back out. then ignores the rest of the food. all my other fish eat the rest shortly after. i cant think of anything that could be making my fish sick.. any ideas? and possible solutions? thanks. Ps.. other than the refugium everything is the same. But he began slowly declining long before the move.
