Tyler, can't really help on locale, but a couple species that Bill Cody has suggested in the past have been spotfin shiners and bluntnose minnows.
No experience with mosquito fish, but have read both good and bad things. The only real bad thing I've read is the niche they occupy in the water column. They tend to stick around the surface and shoreline, avoiding some predation, especially if there's cover. I'll wait for someone with experience with them to weigh in.
