I have no fish now accept two damsels, lost kola tang, yellow tang and two clowns in 3 days. LFS are guys now that just run and acquarium store, loads of salt water tanks, they did not set mine up nor did they sell me anything but the tangs. Coming out today to check my system and hopefully get me straightened out. I am trying not to be discouraged from this hobby but i don't want to kill anymore fish. Will keep you posted. Unfortuntaely noone told me about the sheets for tangs, i will mention that to them and question???? All i have left are my damsels, scooter blenny, cby and cleaner shrimp, brittle star and lots of snails and crabs.
