I've had this guy for several months and no problems. The spots are getting a little better, there is really only one spot now. It does remind me of an infection. There are two long tentacle anemones in the tank and he doesn't really ovoid them so it is very possible he got a little too close. He is eating just fine and if it weren't for the spots you wouldn't know there was a problem. I am just going to watch him and see how he does.
