Should I get a Crab?

[zaku999]

Hi guys!

I am thinking of adding a new coral crab to my 3 month tank!

1) Will my damsels / Clownfish attack the crab?
2) I already have a Fire Shrimp & a Ugly Brown unknown crab. Is it okie to have living side by side?
3) Are all crabs harmless to reef/coral?

Many thanks!

What do you mean by coral crab??? What is the name of the crab you want?
All crabs are not reef safe, some will eat small polyps, acros etc.

I have Emerald Crabs to help keep algae in check, and they're reef safe.

Not at all! The vast majority of crabs are NOT reef safe. I would try and get an ID for the one you have already before adding any more small fish, shrimp or coral to the tank.
