Green Hair Algae
 

I was wondering if anyone has a suggestion for critters that work best for controlling green hair algae. I was thinking a blenny of some kind and some blue leg hermit crabs. Any other ideas?? All my tanks details are below.

blue tuxido urchin and a sea hair will work. I was also told a lettuce nudibranch will work too. Double check that though.

Or a lawnmower blennie. Various snails will also help.

I vote for sea hare.. I had some bad hair algae and my sea hare got rid of it all.... I'd try one of those first.. JMO.

IMO lawnmower blennie's are a better investment. After the algea is gone a sea hare could starve to death, while a lawnmower will tend to eat the same foods as other fish in the tank. Plus they're more exiting to watch.

If you don't have an RO/DI unit, it's a good investment as well.

I have never heard of too many success stories with Lawnmower Blennies and hair algae, and them getting rid of it all. I guess depending on how much hair algae you have he may or may not go after it.

You can always sell your sea hare afterwards or lend him out, etc...

I always wanted a bicolour blenny because to be honest they are a lot more visually apealing, will these have the same effect as a lawnmower blenny? Thanks for all the advice so far, and please keep it coming.

A bicolor blenny will not touch your hair algae.. I have had 2 and neither of them went near it... but they are not known to eat hair algae.

I read somewhere that sea hairs are hard to keep is that true?
