Crab good or bad?

[Swimzebras]

I found a small crab about the size of an emerald crab and of similar shape on my new live rock....tan in clot with faintly banded legs, is he good or bad!?

Try the tilted glass trick and see if you can catch him and then get a good pic of him.

I have a good pic but I'm not sure how to post it using my iPod

[Swimzebras]

I don't think so I mite be wrong check at a pet store near you

 

[Swimzebras]

The closest one is thirty min away and I can't go out now.....what to do?

 

[melosu58]

Hard to tell from the pic. Most crabs are oportunistic (sp) and will take advantage if hungry enough. I would catch him and either put in the sump or give to your LFS.

 

[Swimzebras]

Oh....I suppose

 

[Angelfish56]

What store did you get the rock from

Sent from my iPod touch using Aquarium

School of fish inc. In Springfield Massachusetts. They don't have a website though.....

try to match it up here:
Crab Hitch Hikers

 

[Swimzebras]

Either Mithrax or last portunidae, I think....

 

[mr_X]

you could always let it grow a bit and see what happens, but as mike said, anything with claws has the potential to be a predator.

 

[Swimzebras]

I guess, but I don't have a sump yet......

 

[mr_X]

well, if you are adding one eventually, you can leave the crab in the DT till it's up and if he misbehaves, catch him and toss him in the sump. it will be a bit of a P.I.T.A. to catch though.

I have him pinched in a plastic bag in the DT with part open to the air, how long could I leave him like this?
