The Store keeps all fish in tanks with copper with no rock just fake decor. They said it should be fine. Could it just be becasue I havn't been running my protein skimmer lately???
Could I mabye add some Kent Marine Zoe Expert to boost their immune system and see what happens. Mabye Garlic Extreme????
hey are the brown spots only during nightime ? The yellow tangs have a pajama...during night, their white line on each side becomes whiter, they look pale and they have "bruise" like brown spots...one big spot on every side.
