Best algea eating snail?

[Tarolisol]

A kole tang you say, i guess ill have to look into that, and trochus snails. I think my main problem right now is lack of supply, calgary is lacking at the moment, Hidden reef has informed me they are getting in a large shipment so i think i'll see if they get in any trochus and order some. Also I think a lawn mower blenny may work to keep my sand a little cleaner as well.

Although does anyone know if blenny fish with eachother as i have a Bi color blenny
