Okay I am not sure how much I should be feeding my tank. The clowns won't eat anything except mysis or brine shrimp, formula one frozen food....I have tried flake and pellet but they spit it out. I have been feeding 1/2 cube of frozen in the morning and again at night but I am afraid of overfeeding. The tang eats and so does the cardinal but I haven't seen the gobie eat anything but sand. Should I add coepods for the gobie as my tank hasn't been up that long? and how often should I feed the others? I would like to get them eating some flake food with supplemental mysis every other day???? but I haven't found one they will eat yet. None look like they are starving and the crabs and snails take care of any leftovers..........
