I'd say with about 95% certainty they are coppernose BG... You can see the very distinct striping on them, the classic white edge to all the fins... Great photos for under the water! What part of FL are you in? To my knowledge, GSF are not found in FL, so they are no in the running. They definitely are not RES, as RES are very distinctive underwater when compared to CNBG. They don't appear to be tilapia or any of the other introduced cichlids found in FL... So I'm saying with high confidence, CNBG.
