Emerald Crabs in soon to be Reef

[jehudson]

I have a itty-bitty spot of bubble algea in my tank that showed up soon after adding lighting (this is an expansion of a previous post. I've been researching Emerald Crabs on line and I find some vendors say “reef safe”, some say “not reef safe”. How do ya’ll feel about these critters … yea or nay in a reef?

I've had a few in my tank for awhile and I very rarely see them, but I have not noticed any damage that I could even blame on them

I have never had a problem and most people I have talked to would say they're reef safe.

I have 3 in my little tank, and I had 2 in my 135. I love them. I spot mine alot easier in my small tank as there isn't that much rockwork but I did see it in the larger one also....but they are reef safe. In Missouri, the one I did have was pretty big and he seemed to love the rock that was in the front and center and he would get that defensive attack mode when I cleaned the glass. Never any of the ones I have owned to do do anything but pick stuff of rocks. So I am with the "Yea" crowd.

I am definitely in the YES camp. I have 5 in my 135 reef and love them!

I have had one in my 120gal and after he demolished all of the bubble algae he began to come out during the day looking for food. He quickly became a favorite in my tank.

He also passed away after 6 months...not sure why. He enjoyed eating Chaeto as well.

REEF SAFE!

I have noticed a couple that i have had can be a little aggressive to small fish that get near them. I dont really think the fish would hang around long enough for the EC to get them but they might agrivate them at night.
