27 Gallon Stocking Help

[MarinaClown]

I have a 27 gallon cube with 40 Lbs of live sand and 25 Lbs of live rock. I am running two aquaclear 30 filters (312 gph total) and two starkled flare lights (10x3watts each).

What fish, if any, can I add?

Current live stock:
2 Picasso clowns
1 neon goby
I ordered 10 sps frags to make this sps dominated cube.
Will be upgrading to 60 gallon in 4-5 months when I move.

Have you ever heard of mini pistol shrimps? My LFS is selling them for half the price of a regular pistol. Thanks.
