My two clowns are refusing to eat anything! I've tried mysis, krill, brine, brine w/spirulina blood worms i've even tried giving them regular tropical fish food flakes.They spit it all out! What do I do? Will they get hungry enough and suck it up or starve to death? I have a 55 gallon mixed reefed mostly inverts I only have 2 other damsel fish. the nice, yellow tailed ones, there's no fighting.
