Potters Angel and LMB love?

[grennan]

My Potters Angel exhibits normal feeding behavior, picking at the live rock for algae,etc, but at times thinks my Lawnmower Blenny is a rock. Typically the LMB will sit on the sand and let the Potter pick over him/her, other times the Potter will swim next while picking over the LMB like a cleaner wrasse. I have actually seen this occur for up to 5 minutes at a time. At no time does the LMB look stressed, scared, etc. The LMB is like hey dude/dudette...show me some more love. Both are in excellent condition and eat well.
Has anyone else witnessed this type of behavior? Good/Bad/Indifferent?

My bicolor angel does this to my snails all day long.
Never seen it on another fish though! Pretty funny.
If the blenny doesn't seem to mind, I can't imagine it's doing any harm.

many large angels act as cleaners when young your potter may be doing the same

who knows, maybe you've found out how to keep a potters angel alive in a home aquarium...it needs fish scales to survive...
good luck with it.......
