If you collect from the bays you can get away with room temperature for a lot of fish. As long as you keep your tank in th low 70's they should be fine. Killifish, snails, hermit crabs, windowpane flounder and horseshoe crabs do well in my tropical tank which I keep at 75f. Silversides not so much, but I use them as feeders. Sea robins are cool and found all the way down to Florida.
If you didn't get a tank yet look into the deep blue 80 gallon, the dimensions are awesome. What are your plans for the tank. Lots of small fish, predator fish?
Something like this will cool your tank down several degrees.

Here is a good article about keeping natives. One of the authors goes by paulb on reef2reef. He has kept tons of natives and can give you good information. This time of year you can catch tropical strays. I am thinking of going out and see what I can catch.
