Easily the most recognizable of the Barb family, Tigers are extremely popular for home aquariums. They also are well known for their tendency to nip fins, particularly those of slower moving and peaceful fish such as bettas, gouramis, angelfish and others with long flowing fins. For this reason, they are not suited to all community aquariums. They are best kept in groups of six or more. Tiger barbs do best in soft, slightly acidic water. The tank should be well lit with ample vegetation.
