What eats green hair algae?

+1 for Chitons and Reefcleaners. Totally tore up the GH in my tank.

 

Kole Tangs are bomb, they eat algae like a addict. THEY LOVE IT

 

it actually does look a bit like tiny bryopsis...not sure.

but there must be something feeding the algae, check your phosphates/nitrates!! Maybe you can get it under control!!



And to piggy back off the lawnmower blenny...i also read the detritus thing, and have also read that they prefer film algae rather than long green hair algae.

 

grass eater !!

I have a Red General and 3 Orange Linckia stars that are chewing this stuff up !!!!
Grass on both overflow's !!

 

I purchased a sea hare that my LFS saw eating hair algae. It ate the most algae out of all the cleaners I had in the tank (75 gal). It wouldn't eat seaweed sheets when the algae was almost gone so I passed it on so it wouldn't starve in my tank

 

I have a gold-spotted rabbitfish in my tank that tears up hair algae. He is one hungry bugger though, I can't keep algae on my clips.

Rabbitfish get really big though.

 

a seahare should eat it, but after its good you need to take it back or supplement its diet

 

Three cheers for the algae blenny!

Right about now, I wanna pull mine out of the tank and kiss her right on her plump, luscious, algae-devouring mouth!

Except ... I think she might not like it. ;D

 

I have a Hawaiian Naso Tang and he eats it faster than it appears

 

Maybe you should find out what has changed that is causing the algae to grow instead looking for something to eat it. How old is the tank, what are your nitrate/nitrite levels are you overfeeding the fish, do you have a high bio-load, what is your photo period, are you using tap water? Adding a fish or snail to eat the hair algae is more of a band aid solution as the original cause for the hair algae growing in the first place is still there. Scrubbing and pulling the hair algae off the glass and rocks along with weakly water changes and finding the cause of the hair algae in the first place is generally the best way to deal with it.
