My lawnmower blenny eats algae, but not the long ones... i had to trim mine. My coral beauty also ate all my algae...but they're not always reef safe. I actually miss having hair algae LOL
What do you mean? Why DON'T I have corals? Personal preference....I went into this hobby for the fish, not the corals. I have mushrooms that were hitchhikers on a rock. If I ever get my led lighting set up, I will concentrate on just mushrooms.
On the other hand, I'm very slowly setting up a 20g reef...and by very slowly, I mean at the pace slower than a snail LOL
