I currently have an algae outbreak, too much for any snails salty28. They are attacking what's on the glass and some on the rocks. They may not be the solution to get rid of all algae but they will put a dent in it in addition to other solutions. They are not the fix to the problem of what's causing the algae in the first place but they are there to help, IMO. I'm happy with these guys. Unlike the Astrea which do not right themselves, these can right themselves, which is nice. :thumbsup:
I was thinking of also getting a lawnmower blenny since I have some hair algae going also. I've read they have a personality like the clownfish which is cool.
