After extensive research on Caribbean Biotopes I came up with some ideas on more livestock.
Banded Coral Shrimp
Vase sponge ( please let me know if you have any experience with this, it's been difficult to research. And they are not for sale in many places)
Tube Sponge
Christmas Tree worms
Flame scallop
Millepora Alcicornis - This might be an odd choice but I'm up for the challenge. I might have to special order this somewhere. I've had no luck finding it anywhere online. Edit: just realized this is prohibited in FL to harvest, will probably be very difficult to find. Let's See
Lace coral ? maybe
Scolymia Cubensis/Wellsi - Not sure if this is even available, I think it's prohibited in many places in the Carribean but will look around and do more research.
Ricordeas
With Fish, this tank limits me so i'll stick to my first list I had earlier. Maybe get a deepwater curacao Basslet if I see one on Diver's den in the future.
Feel free to tell me what you think.
