To create an attractive display in a planted aquarium, keep a group of at least 6 Neon Rainbowfish in a tank that is 3ft long or longer. Provide hiding places with plants and bogwood while leaving open swimming space. These peaceful fish do well in a community tank and won't eat plants. Avoid pairing them with larger, more active species. Also sold as Neon Dwarf or Praecox Rainbowfish.
