I agree with Thyra. I made a couple trips to my local pet store and did some pricing, saw which ones I liked an then came back and did some research if they could co-exist etc. But you also gotta let the tank cycle I think its a minimum of 2-3 days( cant remember the exact time ). Someone could correct me on that. So just do a trip to your local petstore. Do some pricing, figure out what ya like and come back and do some research on the fish that you have choosen and then get some fish.
ps
as far as the tank cycling I honestly dont know if you just set it up or have had it cycling for a while lol. Ya didnt post if you just did or have had it set up for whole.
