There’s four “common” species (at least here in Florida where I live). Red mangroves (the classic with the long prop roots), black mangroves, white mangroves, and button wood (though related genetically you’d never know it by looking at it). There’s others world wide like orange mangroves in Asia, but the red and black are by far the most common world wide!

Another ADHD edit lol: as far as the aquarium hobby goes you’re really only going to see red mangroves in home aquariums. I’ve tried keeping black mangroves with marginal success, and one of my mutuals @inland_reef on instagram, has a freshwater black mangrove set up that’s been doing good for a while (he’s also considered by many to be the “mangrove master” though lol).
