Yesterday we visited Sea World. I'm not a fan of theme parks of any sort - but I do like aquariums, and since SW is a bit of both, I agreed to go (instead of, say, walking down the road to the next closest swamp and getting eaten by a gator).
While there, I encountered a freshwater planted tank in their shark encounter exhibit (it was filled with freshwater sharkminnows, with the intent of distinguishing them from real sharks). Turns out Sea World is a fan of Aquasoil, but not so much of tank maintenance - the tank was filled with hair algae and clado. The plants included HC, glosso, Crypt parva, and a few others - not the healthiest carpet I've ever seen but not in terrible shape, either.
Meanwhile, their lake exhibited a patch of really neat Sagittaria
— I'm guessing S. graminea
but couldn't get close enough to confirm. A pity - guess I'll have to try and find a collector-friendly source of the plant, because it looked really cool!
On a more tourist-ey note, I'm not thrilled with the dolphin/whale/sea lion/etc. shows they have, these days. Used to be when you went to something like that, they'd introduce the animals and tell you something about their species, where they come from, what they eat, how big they were, how they care for them - now it's all theatrical, with flashing lights and trainers in costumes and all the animals do is show off tricks. Entertainment without the educational component - which completely defeats the purpose of an endangered/threatened animal show, IMO.
