Brain coral is receding, Need help to try to make it survive. I currently have it in a 24g Nano cube, I feed my tank with Kent Marine Microver5 3x a week and Salifert (All in one) 1x a week. Every other day I will give my 2 fish a damsel and tomato clown some brine shrimp plus. The fish store that I go to in Redlands, Loma Linda is really not that great, just some money hungry bastards that try to sell you stuff that is high priced and have no sort of gaurantee if the fish die within a few hours. So I said F' em, you won't see me buying stuff from them again. So I need some advice, I'm new to this forum so please let me know.
