Shrimp and crab question

[kpatrick]

I currently have a 125 gallon tank with a few soft corals and polyps. I have the following fish in the tank:

3 percula clowns
2 clown gobies
1 hippo tang
1 pajama cardinal
2 cleaner shrimp
25 zebra hermits
2 emerald crabs

I am want to add more shrimp and crabs to my setup. First of all I am looking at the Porcelain crab and Anemonie crabs. Will they be fine in my current setup with the Emeralds and the other fish, or should a stay away from either of them??

As far as the shrimp go, I want to add a couple fire shrimp to the tank and maybe a Pistol Shrimp but are the pistol shrimp safe in this setup ?? I know they use the claw to stun fish in their natural habitat so I hate to hear a loud pop one night and discover my fish stunned and have eaten the next morning!

Along with the crabs and shrimp I would like to add one watchman goby to finish things off, any opinions??

sorry for talking so much
Thanks!

Larger pistol shrimp can definitely kill fish, although I don't know how often this happens. Often, a fish gets too curious and sticks its nose where it shouldn't.

Porcelain crabs are great. They will filter feed and stay out of everybody's way. Unlike other suspension feeders, those guys aren't picky about food size, and tend to do well in reef tanks. I haven't kept anemone crabs, but assume that they will behave like other, less colorful porcelain crabs.

I would stick with porcelain crabs. As mogurnda indicated, they are the same family, but the anenome crabs tend to stress quite a bit without a host anenome, and they don't share well with others--fish and such don't get along well in small anenomes. The standard porcelain crabs will get along with one another, so you can have quite a few together.
