No problem. And yeah, that was some crazy advice lol.
Also, just a word to the wise... if those two fish do have ich, it's almost certain that the other fish have ich as well unfortunately..
Marine Ich is a pretty aggressive parasite, and once it is in the water column, it's going to effect all of the fish that can biologically contract it. I think dragonettes are the only marine fish that can't contract it. Something with the fact that they don't have scales. I think eels too.. not sure about that one though.
