I just noticed this growth on the bottom of my Foxface's mouth earlier today. I did some preliminary research and it seems like it is largely untreatable without serious intervention if it is the worst case scenario, but maybe I can get some better input with these pictures (I tried to get as close as I could in good lighting but he is very shy so it was hard to take the perfect picture). I haven't noticed it long enough to see if it is growing rapidly.
Other than the small growth, he still ate voraciously today both times I fed my tank, and is generally behaving as he normally would, swimming around the tank munching on the rocks and sometimes the sand. As for his diet, I alternate daily between clips of purple/green nori and spirulina tablets. He is a bit of a pig and tends to eat the majority of the meaty food I add in the tank as well, which consists of a variety of marine cuisine, frozen mysis, spirulina enriched brine, and the occasional shellfish (clam, mussel, squid, which I drop in for my wrasse). I also feed formula one and two pellets. Today he ate plenty of spirulina enriched brine and also went to town on the nori clip I added.
I read that these kinds of conditions can sometimes be stress induced, and prior to today he did seem to be acting abnormally (hiding more than usual, flexing his spines under the arch he sleeps in, etc.), which if that's the case, I believe it may be from some changes to my lighting schedule and other additional tasks I have added to my routine to combat a dino outbreak I am also dealing with. I have had him about two months at this point with no other issues.
