They are easy keepers. They do nicely at 78-82F. about 7pH. If the water is a bit acid and dark (or you have a dark background) the colors become more intense. They are fairly peaceful and can get to 6" but 3-4" is more common. In small shoals they will pair off and lay eggs in small hollows or nesting pits. The male is a nest guarder. Feed a variety of foods as they are omnivores. They like planted tanks and use mainly mid to upper water level.
