14 Gal. Biocube Srocking Q's

Hey there, I have a 14 Gal. BioCube (was a gift) that was home to a small mantis. Sadly the little guy died and now I have an empty tank (well, save for the small CUC I just put in).

I would love to have a mantis again but so far no dice on finding any.
So, I was wondering if anyone could toss in some suggestions aside from the obvious fish (gobies, etc).

What's something unique and sensible to put in there?

Thanks!

(Bah, STOCKING. Why can't I edit titles?)

 

a staghorn hermit crab!!!

 

Those critters are awesome!
However, I'm a bit new at this and it worries me I wouldn't be able to care for it properly.

 

Nothin'? Come on, get creative!

I sure as hell can't. Lol.

 

Check out Colin at coralmorphologic.com. I would go with an insane ric/st. thomas tank with one of his translucent shrimp. The color combinations you could come up with are endless. Plus they are easy to care for.
