The Harlequin Rasbora is a fine example of the Cyprinid family of fishes. They make a colorful and lively addition to any community aquarium. A planted aquarium will give them places to dart in and out, as well as set off their fiery color. They are great for people who easily become bored with fish, they swim about constantly and can be a bit boisterous! Not to be kept with shy or slow eating fish, they do well with other lively Cyprinids like tiger barbs and cherry barbs.
