Aquarium Condition

Rummy Nose Tetra is considered to be whimsical in the aquarium and is more suitable for experienced breeders.

These tetras are medium-sized and live in a flock. They love to swim actively, so their aquarium should be a volume of 50 liters or more. For the bottom decoration, you can use gravel or coarse river sand.

Since the fish are shy and love to hide in the thicket, it is necessary to plant aquarium plants. For decoration, you can use snags. It is recommended to put some dry leaves into the aquarium, which will create a layer at the bottom. Such an environment will resemble a natural biotope.

It is better to place the aquarium in the back of the room, where the fish will not be disturbed by loud noises and crowds. For the comfortable existence of the rhodostomus (Rummy Nose Tetra), certain water parameters are necessary :

  • temperature – 22−26 °
  • hardness – 6-15 °
  • acidity – 5.8-8 pH.

Rummy Nose Tetra is sensitive to a high content of nitrates and ammonia, so it is better to install an external filter, it cleans better.

Water parameters should be checked with special test strips purchased at an aquarium shop. A deterioration in performance is indicated by a change in color in the fish to a faded one.

Lighting should not be too bright; Rummy Nose tetras prefer the shading effect. A water change should be carried out weekly in the amount of 25%.

Any kind of Flocking fish, which include Rummy Nose tetras should be kept in an amount of at least 6-8 pieces. This species does not have a pronounced leader, tetras frolic in water altogether.

Rummy Nose Tetra Tank Mates

As tank mates, other peace-loving fishes like Angelfish, Harlequin rasboraneon tetrapygmy corydoras, betta fish, or discus fish are perfect for them. Pygmy Corydoras and Tetras normally live with rummy nose in the wild too so they are very much compatible!


Rummy nose Tetras should be fed 2-3 times a day in small portions and make sure the food is completely eaten within 3-4 minutes. Rummy nose happily enjoys eating dry food, frozen bloodworms, artemia, and tubule.

Occasionally you can give grated vegetables so that the fish do not eat the leaves of aquarium plants. The more diverse their diet, the better their immunity, and better health.

Breeding Rummy Nose Tetra

Breeding Rummy nose Tetra can be called a painstaking task which requires special attention. This is due to the fact that the fertilization of eggs requires perfectly clean water. Another obstacle in this path is the slow growth of fry.

To breed these aquarium fish, you need special types of equipment with a UV sterilizer built into the filter. Processing the aquarium with ultraviolet light will produce water of the required quality.

The Rummy nose Tetra to be bred should grow in acidic and soft water. Before putting the fish to spawn, feed it with a live feed. Tetra’s reach puberty by 8−12 months, if they grew up in the right environment.

From this moment it will be possible to determine their gender. Before breeding, males and females are kept separately in softer water, which is 1–2 ° C warmer than usual and has a pH of 6.6–6.8.

Specialists recommend preparing water for spawning in a special way. To do this, mix rain and distilled water, add a little water taken from forest puddles, as well as a decoction of peat. The mixture is filtered and poured into the container a few days before spawning.

At the time of tetra colonization, water should have a temperature of 25–27 ° C, the hardness of 2–6 °, and pH. Compliance with these parameters increases the chances of successful spawning.

One must take into account that the number of males should be twice the number of females.

Rummy Nose Tetra Fry

The entire spawning process takes about 10 days. Males actively care for females, and they try to hide from their harassment. Spawning must be covered with glass from above, otherwise, the fish may jump out.

Finally, tired females give up and go to spawn. The process begins in the evening, in the morning the tetra’s spawn. To prevent eggs from being eaten on the fly, they set a grid in the spawning grounds through which they fall to the bottom.

After spawning ends, the parents are removed from the aquarium, and the eggs are shaded for a day. Then the net is removed, and the water level lowered. Fry appears on the 4th day. Each female is able to lay up to 400 small eggs at a time.

Offspring are fed several times a day with infusoria and “live dust”. By two months of age, fry reaches the size of adult fish. Red-nosed tetra can spawn up to 8 times a year.
