Anyone seen a Lawnmower Blenny in Calgary

[sharuq1]

I've run into a small hair algea problem and thought a lawnmower blenny might help solve the problem - not to mention they have a neat personality. Anyone seen one in Calgary?

Also I don't have and substrate is this going to be a problem or do they care?

My blenny wouldn't touch GHA, but maybe you can find one that will. I never had any problem with mine in a BB at all. Another critter you could consider is a sea hare.
