Hello, I’m new to the reef community and got some pretty bad advice to start out. Neverless definitely learned a ton over the last few months. Now I can’t see to find out what’s wrong with my fish I’ve tried treating him a few different ways from things I thought it may be but the spot keeps getting larger and his health seems to be declining everyday, got the spot about two weeks ago when we were on vacation and came back to this it’s almost doubled in size in about a week. I’ve used ick care and Pima fix on some recommendations from a local shop but noting. Plz help asap don’t want to get worse or lose our dotty back
