Need Advice: Kole Tang, Mouth Fungus?

[aquasalt]

I recently moved our Kole Tang from QT into the Display Tank. He was in QT for 4 weeks and doing great. Tonight I noticed his mouth looked very swollen. He appeared to be acclimating beautifully in the tank and eating, but for the past two days has seemed melancholy. He was introduced about a week ago.

Other inhabitants include a Hippo Tang, 2 Banggaii, 2 Firefish, 1 damsel, skunk shrimp, and blood shrimp. Everyone else appears to be fine.

Looking for advice!

I had that happen to a tang once
I am not sure if it got stung by a coral but my cleaner shrimp did the trick cleaning it often and well

Thank you, Joanne. I don't have an corals at this point, but I do have a cleaner shrimp in the tank so fingers crossed. His condition has not gotten worse; in fact there may already be some improvement. He is still picking on the rocks so that's good sign.

A quick update: Kole Tang seems to be doing much better...his mouth appears a lot less inflamed. I believe it may have been stress and/or him nibbing at one of two aiptasia (that I need to get rid of).

Now onto the next mystery...I have managed to lose a blood shrimp and firefish all at once! They have mysteriously disappeared and it is driving me nuts. I have looked everywhere!

I guess I will just continue taking 1 step back for every 2 steps forward.
