I know you wanted a single wet pet, but you could do a breeding pair of Discus. I've personally found that Discus are pretty interactive. My pair always followed me around, and they were delightful to have.
Plus, there are a few bonuses: If you change your mind later and want to create a community tank, a Discus pair would be great for a community tank as they get along with practically everything (I paired mine with everything from tetras to catfish and medium to small cichlids). Also, you could sell the babies to make some decent cash to support your hobby.
