Have one pincushion, it seems to do a good job at eating algae. It's a bulldozer though. Seems to have little care about what or who it climbs on and every little piece of rock, shell, or whatnot gets stuck to it. It's like a traveling junk pile. Oh, this one lives in a little 29g reef tank. To date it has not caused any harm to any corals that I have seen.

Sparky, they do that for camouflage, mine carried around an old hydrometer for a day or two!

HI,

I got two common urchins (like brown hackeesac) but they don't touch my hairy green algae (like Don King's hair) at all. Those are a pain to remove. Any suggestions? Dai

Take your index finger and thumb, place them together while grasping a clump of algae, and pull... Repeat as needed.

I hate that stuff and manual removal is just about the only thing I have found that works.

PROS CORRECT ME IF IM WRONG PLEASE!!
Im still very new at this and I dont have a lot of green hair algae, but i kind of nipped it in the bud when i started my set up, I know it thrives in low water flow and with heavy feedings (high nitrites) I have a high water flow and im not a heavey feeder of my "fish" they eat probably every 3 days but my emerald crab seems to like it along with my turbo snail and ive heard alot about sea hares really being the only thing that specifically will eat it and pretty much all other algae but when the algae's gone the sea hare will starve to death, foxfaces and tangs are good to but every tank is different so what works in mine might not work in yours i dont have a lot of algae period except coraline so thats probably why my turbo snail and emerald crab do the job, the best thing i can tell you is if its bad scrub it off with a toothbrush to get the majority off and then maybe your "cleaners" will control it if you dont have a turbo snail id say snag one or two and a couple emerald crabs to start with depending on your set up if its reef your carbs should be fine but if your FO or FWLR they might become a meal

Juice, the hair algae thrives off of nitrAtes and phosphates. My pencil doesn't seem to eat hair algae as much as my pincushion. I honestly beleive the pincushion is really eating the coraline and anything that is on top of it, so I don't think their diet is really hair algae....
