I have a friend who recently got into the fish hobby ( I guess I rubbed off on her a bit). But, she got a rather small tank, 1.5 gallons, and the only fish I know of that can live in that size are bettas, and that's still a pretty small tank. She's a bit picky with her fish and wants something original so I have not idea what to recommend. Are there any fish that can thrive in that small of a tank and are "original" ?
