emerald crab


Recommended Posts


um, I HAND FED my emerald big chunks of hair algae (green) and it ate it all up.

It ate up all the red hair algae too..

and then it went for the bubble algae

and then for the coralline

and then for the dead percula clown

and then for my macroalgae


in my experience, they'll eat up your hair like none other.. i'd say a very bad case in under a week. but it's nfot worth it in the long run. My crab in my ten gallon is fully grown, and is very vicious at eating coralline and it breaks apart fragments of live rock.


go for hermits

will the hermits do as good of a job, if so which kind just red and blue or do they all pretty much work equally. I figure if I go hermit I need like 4 for the 12 gal, correct?

Try blue tuxedo or hairy pincusion urchin. These are excellent eaters of bad types of algae, including hair algae. I have a blue tuxedo and its done a great job on the hair algae and red algae in my tank. Also, I have had good experiences with emeralds and bubble algae.
