Bored of CUC, help me choose another

The cleanup crews in my tanks are starting to bore me, so I thought I'd expand. I'm down to just hermits in my 29, and wanted to expand.
I still have 1 Nass and 4 Bumblebees in my 12, but if the BB's aren't reef safe, they go to. (They seemed cool at first, but they hide all the time).
I know I'm going to pick up a couple Nass snails once they're in stock at my LFS for the 29, but what else is there on the crab/snails frontier?
As far as other things, is a 12 big enough for a fire/cleaner shrimp? Is the 29?
Also, I have a Shrimp Goby in the 29? Should I get him a Pistol? Will he shoot other fish with it?

Lots of stuff but with a small tank you'll have to supplement their feeding. Here are some inverts to look into that are often available at LFS. Astraea snails, Mexican turbo snail, cerith snail, emerald crab, sally light foot crab, pom pom crab, decorator crab, and brittle starfish. Some crabs aren't really algae cleaners but I love the inverts. Check out some shrimp too. Most shrimp are compatible as long as it's not a coral banded shrimp and you can have several shrimp in your 29.

I keep a cleaner and pep shrimp in my 14G BioCube. Looking for cool inverts check out the pom pom / anemone crabs or the decorator crabs.

Thanks guys. I know LFS has a selection of shrimp right now (which is rare) so I'll probably pick one or two up this weekend.

I like the idea of pom-pom and decorator crabs, but have never seen them 'in person.' I'll guess they'll have to wait until I put in my 'big order' with SWF when my wife let's me upgrade this summer.
