Nissan look into Trochus sp snails... aka zebra striped turbos... but they are not Turbo sp. They look slightly different, they have a black foot and small antenna that stick out all around them like curb feelers... LOL. I bought 4 just to take out my hair algae. They love the stuff... however just like with a LMB which will eat it, just not as much. You need to make sure its not long and flowing. You may have to manually cut it down/brush it. Then those guys will go in and take care of the rest. I know my LMB will tackle any hair algae that is just a small covering and so will my Trochus snails. And yes even my tiny blue legged hermits. What people dont realize is when its long and flowing those guys want nothing to do with it. JMO/E
