Suing my previous landlord in small claims court?

I was living in Gainesville FL for the last year in a 4 bedroom apartment with 3 other room mates. The landlord had asked me to sign up for utilities in my name as I was the only one who had good credit and would not have to put down a deposit among the 4. He would them reimburse me for the other 3 occupants share of utilities at the end of the month (they used to pay him rent+util directly and then he would pay me their util share). In December I moved back to Atlanta after I lost my job in Gainesville. My landlord owes me $200 for the utilities share of the other 3 room mates for the last month I was there. He is now not picking up my calls and ignoring my emails. Can I successfully sue him in small claims court? We do not have a written agreement about this utilities arranagement, it was verbal.
