Weird protuberance on Anthias dispar's nostrils

[avorio]

Hello everyone! This is my first post here, although this forum has already been super helpful for research. Thanks, all!

Yesterday, I noticed a super weird white protuberance on one of my Anthias dispar's nostrils. It wasn't there before. They live in a group of three, and only one is demonstrating that. All of them are eating just fine.

Any ideas on what this could be?

PS: Apologies for the poor quality of the photos; it's a big challenge to take a good one.

Welcome to Reef2Reef!

Not sure what that could be - perhaps a bump/knock on its snout?
How long have you had this group?
What is the water temperature? They seem to be breathing a tad deeper/faster than they should be….
