Oh wow you’ll have a blast in Florida then.
I’m excited for you haha
Like others have said, coral corral is cool. Nice big display tanks. Marine warehouse is very close to that and has a decent selection. That could be one easy trip. I live over in Brandon/Valrico and my LFS is “The aquarium and fish store” (original name, I know). They have some nice stuff for good prices but not as flashy as the previously mentioned 2.
Then if you have time make the trip to Orlando and stop in to WWC and Top Shelf.
I think both WWC and Top Shelf have insane prices, but if your goal is just to enjoy some beautiful display tanks that will 1000% check the box.
The drive from St Pete to WWC is about 1.5 hours. Probably closer to 2h with traffic depending on when you go.
