Emerald crabs in a reef

[Reef_Boy-88]

I recently cycled my tank and I entered the ugly stage so I got some clean up crew. My LFS recommended some emerald crabs along with a handful of other things. After I took them home and put them in the tank, I did some research because I thought that I’ve heard emerald crabs aren’t reef safe. I currently have 2 anemones and I am going to add more corals soon. Will the emerald crabs eat my corals? Should I take them out?

I never had an issue with mine.

Mine was nipping at the base of my torch’s and other LPs I put 6 in and they all gravitated to my LPs they had to be removed

If it's got claws, it breaks laws.

Except for porcelain crabs. Porcelain crabs are cool.

Cleans the tank pretty good. Occasionally I see him pulling some suspicious moves but no damage.

Agreed porcelain crabs are the stuff they are so cool. I have one hosting an anemone I found his malted shell for the first time, and I like to have a heart attack because I thought he had passed away but he still there being cool.

Interesting you chose to add a couple nems after cycling since they are more of a challenging addition to a new tank. How are they doing?

I haven’t seen problems with mine. But I rarely see it.

Have had a total of 4. First was a monster eating coral. Next 3, they just eat algae. Keep An eye on em.

I like mine

Mine kept picking at zoas and palys and got a face full of toxin and died. Took me a little to figure out what was killing them until I saw one picking at them and then fall off the rock, dead when I picked it up! Thats the only issue I ever had with emeralds otherwise they are fun little dudes!

They are doing really good. I bought them from a guy along with the clowns and he said his are really hardy. Once I put them in they closed up a bit but other then that the clowns have already started to host them and they have been doing great!
