Are Emerald crabs bad?
 

Do Emerald crabs tend to eat snails and invertebrates? We just bought one and now I am second guessing the purchase.

well I had a bunch of snails and hermit crabs along with emerald crab and the the hermit crabs ate my snails not the emerald crab.

Why?
 

Why are you second guessing your purchase?

They only eat algae

according to everything I have read, emerald crabs are considered reef safe.

if they get hungry enough they may eat some polyps but they are mostly reef safe

They are very bad, you should give it to me :wink:

mine eats more coraline than undesirable algae.

Another Note
 

Crabs are crabs,,they should all have an early encounter with a Mantis.:lol:

My emerald did kill a snail when we first got him.......I'm not quite sure why but he hasn't touched another one since. Funny thing with him is I won't see him for a week, sometimes two and just when I figured he off and died, he shows up just to make me happy!

I paid $9 each at J&L and will buy more.
