Hey everybody! thanks for taking the time to look at my question. I just set up a new tank, used live rock and some sand/coral with bacteria already in it. I picked up some damsels and a percula clown. my salinity is a little high and i am worried and messing too much with it. the yellow tail damsels and percula are fine, but i have lost 2/3 domino damsels and the last one is swimming a little funny. what should i do?
