Lawnmower Blenny in SPS tank
 

I want your experiences with Lawnmower in a SPS tank. Good, bad?

I've had my LMB for a couple years now. Great reef fish that never bothers any of my coral including SPS. Also good with clams, as I already mentioned in your other thread.

thanks ;)
I got scared 2secs reading on liveaquaria taht they can bother SPS (and clams) :crazyeye:
I add one this week end to help controling the algea ;)

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.

Not a problem in my experience with SPS.

Nope, me neither. He's a model citizen.

Nassarius Snails
 

My LB would go after the Nassarius Snails... He was never successful at killing any of them. That's the only thing he went after.

If by bugging your coral you mean perching on them for a few moments before searching for more food.. then yes, they are all guilty of that. As for doing any real harm.. never heard of it.
