Lawnmower Blenny in SPS tank

[xtreme]

Hmm, I have never thought of them as a risk to SPS and clams. As with most fish in this hobby it can be hit and miss. I should also mention my lawnmower is well fed. I would imagine an underfed fish would be more likely to nip at polyps.

My bicolor was a problem for a little bit nipping at my sps but maybe he was seeing if there was algae on them? After I had a few more fish in the tank he started spending more time in his cave and less time perched/mouthing the corals.

Not a LMB but still maybe useful.

For some reason I can only keep LWB's alive for about 3 years at a time. The 4 that I have had over the years have never bothered any corals or clams at all.
