Hi, everyone i just got 3 new frags......i believe they are acroporas. two of them were bought at that fish place and they didnt give the name......they were just labled assorted. the other was bought at a local store and i believe its called a green slimmer. the green slimmer still has some color to it but polyps havent been out on it since i have had it. one of the others has color but on some branches is turning white. the other has just turned straight wihte no color at all. i have had them all roughly 5 days maybe more. What should i do? Whats is wrong with them or my tank? a friend of mine sayed that they may not be getting enough ight.........?????
