So I'm taking my prized Coral Beauty to the lfs to go in the QT. He is covered in ich- he's showing signs he's feeling like crap. Now, I heard that some gobies and others alike sometimes will not get the ich on them when others in the same tank get it. I have a Yellow Watchman and Purple Pseudochromis, they both LOOK fine, but I am hesitant to keep them in the tank. I need yalls' opinions PLEASE!! Thank you!
