I think in Florida golden shiners are a good choice. A much better choice than tilapia. You may also want to consider lake chubsuckers. Do a search on here, we have talked about them much recently... Todd Overton just started selling them this year. They are rather common in most lakes in Florida and IMO are a top notch bass food... You may be able to collect some from the wild in FL as well.
