Lawnmower blenny problems

[johnehr]

After I finally get my lawnmower looking good (he had trouble eating) I noticed a white bite mark? on his body right where his top (dorsal?) fin meets. Its probably about ~1/8" in diameter. Its slightly visible from the other side. It seems too large to be any parasite (I can see that its a slight depression). Do you know what might cause this? I dont think its disease, but would be surprised if someone bit him.

I'll take some measurements but think its all fine (except calcium might still be 500+).

My tank:
60 gallon
140 lbs live rock
1" SB
1 6 line wrasse
2 bangaii cardinals
2 percula clowns
1 firefish
1 flame angel
1 yellow tang
1 cleaner shrimp
2-3 peppermint shrimp
turbo snails
2 emerald crabs
various lps, softies, and a tiny RBTA
and a bristle worm to boot.

Lawnmower Blenny Picked on

Hi John I too added a Lawnmower Blenny to my 150 reef tank and it was picked on alot by My Tang's esp. My powder Blue he would chase the Blenny for sport i think. Mine finaly got tired of being chased and rammed to powder head on and that was it no more who's the boss in my tank. I think the Lawnmower Blenny will Let the Tang know when its had enough. JMHO :|
I hope this will Help John Best of luck ..Jeff
