2 emerald crabs in the same tank?

[fungia]

can you keep two emerald crabs in the same tank? my tank is 100g, i used to have a 40 gallon and one crab would kill the others.

I did it without any problems. 100g is well enough room for them to find spots of their own.

I have had 2 in a 37 reef tank for about 8 months w/no probs. One is def. a male and the other a female.

i have had 6 or so in a 75 with no trouble, but watch them..they may pick at corals. mine did.

i had about 5 or so in the same tank, the only thing is some grow much much faster than others, i noticed when one got large it killed the smaller ones. if they stay the same size you should be fine. they are cool looking crabs, i miss having them i noticed they were picking at polyps so if you have corals you have to watch them even though they say they are reef safe. some people have no problems with them at all but i did on more than one occasion so i left them alone for now.

They will do fine in your tank together, but I am not so sure about your corals and other critters.

I used to have 5 in my 180, but yanked all out after all sort of destructions they done.

Now I only have a small 30G tank, and I wouldn't put any crabs into my tank, not even sally light foot.
