I used to keep them. Their basic care is no different from any other fish apart from that they are very difficult to feed anything but live fish. They are best kept in a group of at least 3 and require a large tank for their size, a 55 gallon is the minimum id recomend keeping them in, anything smaller and they will smash their beaks against the glass and then starve to death. Dont keep them very active middle dwellers like large barbs and characins as they are easily spooked and when frightened will try to jump often hitting the hood so hard they kill themselves.
