what to put in my new 12g

[stuie25]

so ive decided for my first tank that im going to start small even thought ive herd thats harder.

I purchsed a 12g compleate cad lights setup and a koralia nano. Im going to try and work with the stock light for now.

i currently have a 60 tank full of live rock as well as a pair of hermits, a pair of cleaner shrimp, a turbo snail and a pair of clowns. I bought it all for 240 bucks from a friend that was getting out of it. it was too good to pass up but the tank wouldnt fit anywhere but the bedroom and the girlfriend hates the noise so its gota go.

what if anything else can i put in my 12g , or do i have too much allready.
