Rummy-nose Tetra (Hemigrammus rhodostomus) is a calm freshwater aquarium fish with compact size and is prized because of its reddish-colored nose and brilliant black-and-white striped tail. With silver appearance and iridescent flake scales, it looks incredible in planted community aquariums.

Both sexes are similar in color, but the females become rounded on maturation. These tetras are active schooling fish that make a fascinating sight when maintained in schools. They are hardy, sociable, and suitable for beginners as well as intermediate aquarists interested in active community tanks.

Origin of the Rummy-nose Tetra

Rummy-nose Tetras occur naturally in South America, that is, in Venezuela, Colombia, and the Brazilian river basins of Rio Orinoco and Rio Negro. They occupy slow currents of rivers, streams, and soft acid water floodplains that are thickly vegetated. In nature, the tetras school in incredibly large numbers, which helps to hide them from predators and facilitate them to swim normally. Being bred and maintained has made them that common for aquaria.

Temperament of Rummy-nose Tetra

Rummy-nose Tetras are very peaceful and non-aggressive and extremely social. They are relaxed with a minimum of six or more of their own species, which serves to decrease stress as well as increase schooling behavior in a very natural way. Although they will chase one another intermittently within the school, this is to be anticipated and will never be aggressive. Their schooling behavior and active swimming movement render one of the prettiest fish to observe in planted aquaria.

Compatibility with Other Fish

Rummy-nose Tetras may be kept in community aquaria with other serene fish. Suitable tankmates are:

Neon tetras, Cardinal tetras, Ember tetras

  1. Corydoras catfish
  2. Tiny livebearers such as guppies or platies
  3. Serene rasboras

Do not keep large or hostile fish such as cichlids or barbs as they will harass or feed on them. They are safe and relaxed as long as they are held in a school of six or more.

Price Range of the Rummy-nose Tetra

Rummy-nose Tetras are cheap and relatively available. They sell at between ₹100 and ₹300 (US $1.50–4) per fish. Because they require schooling, aquarists will buy some at the same time in a way that they will have enough schooling behavior.
