The African butterfly fish, Pantodon buchholzi, is an interesting fish; I had a pair for several years quite a while back, in a 15g and then a 20g. They are not particularly active, but do appreciate floating plants and warm water. The tank must have a cover with no extra openings around filter, heater, since they will jump; they "glide" above the surface and there is some evidence that they "beat" their pectoral fins much in the manner of the SA hatchetfish.
I would recomend a longer tank that a 10g, and a pair (males and females can be sexed fairly easily by the anal fin). They will be more relaxed than one fish alone. The tank need not be very deep, so a 15 or 20g long is fine. They usually attain 4+ inches in a suitable aquarium; floating plants, and some twigs reaching just above the surface help to keep them calm. Small live crickets are an excellent food, along with worms, insects, prepared pellet-type foods that float. They will readily snap up any small fish that come to the surface from below, in case you're thinking of tankmates.
