what is on my Gramma's fins?

[copi]

I woke up this morning to find sand stuck to two fins on my royal gramma. Looks like either sand is stuck just to the end of the fins (unlikely), or maybe some kind of worm on each fin (sand sticking to the worm's mucous?).

Sorry that the picture isn't the best -- I have no idea how you folks get such clear shots.

I don't know what to make of this. Should I be worried? Thanks.

Keep an eye on it for sure but I think you'll find it's just sand. The fish was most likely resting on the bottom and it's own slime coat had trapped the sand. It will most likely be gone later today if so.
