Lawnmower Blenny question

[mrpenguin]

I can get some Lawnmower Blenny's for very cheap ... I was wondering how many of them I can keep in a 75G.
I would like to be able to keep two ..... will they fight ? or can this be done ?

Also, can I and should I keep one of these in my sump ? I have a lot of algae on the glass there and I never bother to clean it.

i've seen them become fairly aggressive towards one another, so I'd say to just stick with one.. and i've seen some that eat hair algae, and some that don't even touch the stuff.. some that eat frozen, and some don't..

maybe you can pitch him in the sump for a while and put him in the display when or if he decides to eat all the algae

Thanks ... but what about keeping one in the sump at all times ?

I personally would put one in a sump -- can't be assured that it will eat the algae on the glass. And if it did, would there be enough to keep it alive. Put a couple of snails in there in stead.

And I agree about only keeping one if you put it into the DT.
