My new blue tang had white marks on his body, (they looked like chalk markings), those went away; all but one. Now he has small specks over most of his body like tinny salt granules. I'm pretty sure it's ich, the other fish are now flashing on the montiporah and sand (sp? my spelling sucks). The red headed fairy wrasse has the same specs on his fins and empennage. My question is now that there are two clowns, yellow tang, fire goby, blue tang, and a fairy wrasse what do I do to resolve this issue. From what I've read copper is out of the questions as I have 26 corals in there.
