hairy brown algae???????

[threex]

I know its beneficial, but what type of crab or snail will eat it. My coral banded shrimp is loosing its red and white color and starting to turn brown from it.

My Yellow Tang is the best at attacking hairy algae. The blue and red legged crabs are great too. I have Astera snails that do a good job on the glass and LR. I was told the one crab or snail per gallon was the rule of thumb on cleanup crews.
