Emerald Crabs, how many?

[kev]

I was at the LFS the other day, and I noticed these cool little guys. I was wondering if they are ok for my 20gal, and if they are, how many should I get?

with a 20 gal tank you could go with one they do cover a pretty good area and may end up with territoy disputes if overcrowede. they do like to eat bubble alge also

I had 4 in my 75 gal. and 2 of them developed a taste for softies and LPS's. Keep an eye on 'em.

Will a 20 gallon be alright for keeping this 1 Emerald happy?

The rule of thumb that I've read for emeralds is one per 25 gallons. One should be fine in your 20.
