Bio colour belnny nipping acros??

[fishkeeprian]

Hello,

I think my Bi colour blenny is nipping at my acro. I say this because I've seen him nipping around the base but thought maybe just cleaning up the plugs, but I have seen what appears to be bite marks on various places on my green Bali slimmer, anyone else had any issues?

Yep, mine did the same. It seems to be quite normal behavior for them.
