I have a recent addition to the tank and it's a Pink Streaked Wrasse. I'm noticing he has some sort of white spot on his left side that looks like a cut/wound. Any idea what this might be? His behavior appears to be the same (and improving as he becomes more confident in the tank). No spots on any of the other fish.
Depending on what the diagnosis is, is it something that can spread to my other fish?
