spot on my yellow tang

[Lmecher]

It is on the tail. Any ideas as to what it is?

 

[MrTuskfish]

I can't tell. I doubt its anything to worry about. Does this appear to be a separate "critter" or just a bulge within the fish?

 

[Lmecher]

It is raised but difficult to tell if it's a parasite or actually inside the fin.

Has the fish's behavior changed? Eating? Hanging out in a corner? Rubbing against rocks? Hiding?
I usually don't worry about things until we see a change in behavior and a lack of appetite.
If you see any of those changes, I would ensure my water chemistry is good and perhaps add a little garlic to the food.

1. Observe
2. Check water parems
3. If 2 is good and 1 is abnormal add garlic to food.

No behavior change or appetite. I will keep an eye on him and revisit if there are changes. Thanks for the responses and advice.
