emerald crabs

[coralreefer]

do they eat bubble algae? if so, how many should i put in my 75 to clear it out?

 

[nycbob]

if u hv a lot, start off with about 3. otherwise, 1 would do.

I would also incorporate the siphon method

Still yet to see any of mine or my buddies touch buble algae....

Mine doesn't eat bubble algae, but I have seen them eat it before at the lfs...
Mine however absolutely loves hair algae.
If you haven't already, remove as much as possible and see if and how fast it comes back. I would get emerald crabs anyway though, because they're awesome!
Good Luck with your algae woes
