Sorry to have to tell you this but Specks don't like (can't survive) water that's too warm so I doubt you will find very many Specks below Lake Okeechobee. That's probably why they aren't mentioned by Miami Metro-Dade folks. There are a lot of exotics down there though like Oscars and Mayan Cichlids in addition to the fish you mentioned including bream, carp, catfish, gar and so on . You "might" be able to find a few Specks though that are in really deep waters (where its cooler). If I were you and living down there, I would take a trip up to the Big O for Specks.
