Eel at Sea Life Aquarium, Benalmadena
Although it's small, the Sea Life aquarium is quite well-done. It has a lovely shark-and-turtle exhibit, but otherwise it mostly focuses on Mediteranean fauna, like octopuses, rays, seahorses, jellyfish and eels (which, as you can see, look very cool under blacklight).
