Lawnmower Blenny?

[noo2usa]

Why is my lawnmower blenny nipping at my rocks? And will he eat my coral?

That is typical behavior for them, he is eating the algae off of the rocks. If you let the algae grow on the glass for a few days you will have little kiss marks all over the tank. He shouldn't bother the corals but there is always a slim chance.

he should be eating the algea thats on your rocks. I got one for the hair algea in my tank and he was always nipping at the wall and the rocks. I dont think you will have a problem with him eating your coral. Mine hasnt done any damage.

He is eating the algae but it looks like he is busting little pieces off. I have also caught him hassling my snails and hermits.

Do your rocks have algae and stuff on them to eat? Has he been eating prepared food at all?

I haven't actually watched him eat. My schedule is crazy so I don't have the opportunity to watch them like I would like. I have put herbivore flakes in the tank for him but I don't know if he's eating it. It looks like he is eating the hair algae.

A few years ago my kids nicknamed it the headbanger because of how he eats the algae. I had a regular lawnmower several years back and now a stary blenny. I have clams, sps,lps and some zoas and have never had a problem with them. But, like skins said you never know for sure.

I'll keep an eye on him but I think everything will be ok. He is a lot of fun to watch...

Good luck with him. I had one when I first started in saltwater and they are fun to watch for sure. I love watching most blennies for that matter :)
