I had 5 fish, a 3 stripe damsel, yellow fin damsel, yellow watchman goby, formosa wrasse and a clown. I am down to the wrasse goby and clown. I first noticed the scales of the 3 stripe were wierd looking, then his gills looked jagged, he 2 days later died, my yellow fin damsel got a whitish brown spot on its head and what appeared to be a breathing issue.. it in 2 days was dead, my clown and wrasse and goby seem to be fine. Even if i wanted the goby out to QT i couldnt get him out as he wants to hide in his holes in the live rock. My clown seems to have a small symtoms and light specs on him, no other fish seem to be showing signs of anything no breathing issues or anything that i notice. I have a few corals in my tank, and I have an 8 gallon biocube with crushed coral substrate running empty..

Can I treat the tank without killing my corals? I have soft and hard..

I am missing posts here. I see S-L and then S-L responding to someone else and I have no one on my ignore list!
Salt-I had this, and this is why I push QT. I had to use Formalin 3 in QT. Copper didn't do much. But that is not a good treatment for the goby...copper or formalin. And gobies can get it if a damselfish is not around to play host.
This is assuming that this is what you have.
This is also why I have a UV Sterilizer! Not as nice as plain old ich!
