Attack Of The Blenny(s)?

[Poseidon]

I have a lawnmower blenny who is a bit of an a**hole.
he like to bully the other fish, but the tank isnt over crowded and everyone can easily get away, hide etc.

Now ive noticed, twice, once on my yellow tang and once on my blue throat a white circular mark on their side.
Exact size of a blenny mouth......
After a couple of days the 'wound' disappears and i haven't seen it again.
Do you suppose the blenny is actually to blame?
Anyone had this type of behavior before?

I have plans to get a Midas blenny in the future. Im wondering if this little guy will have to go first....

Yes, I have a starry blenny and when he wants to be a dink he will be, just as you say.., my foxface has the same thing happen once in a awhile, almost like the blenny got mad he was eating his food or something.
