feeding

In the wild, rummy nose tetra feeds mainly on small invertebrates. In the aquarium, rummy nose tetra can be fed with high-quality and not too coarse dry food. Feeding live and frozen food, such as Artemia or mosquito larvae, comes closer to the natural diet but is also associated with more effort and costs. On the other hand, red-headed tetra, which is fed with live food, show a stronger and more beautiful colour. Many aquarists use dry food as a staple food and feed live or frozen food once or twice a week.

breeding

Rummy nose tetras are free spawners and are now being reared in large numbers. The eggs are shed between plants or other suitable spawning substrate and adhere to them. As they are strong spawn predators, it is advisable to remove the parent animals after they have laid their eggs. The young hatch after about two days, and after four to six days they can swim freely and be provided with fine food.

Water values

The rummy nose tetra feels at home in soft and slightly acidic water. In its homeland, the rummy nose tetra lives in blackwater rivers. It is ideal for keeping it in a black water biotope aquarium, but it can also feel good in clear water. Rummy nose tetra is very sensitive to water polluted with nitrite and nitrate. Therefore you should carry out a partial water change and water tests at least once a week.

Facility

The aquarium equipment should be based on the natural habitat of the rummy nose tetra. Dark sand or gravel is suitable as a substrate. Rummy nosetetra feels at home in rather dark, shady areas. To do this, you can dim the lighting a bit or use some floating plants to shield the light. Stones and roots made of bog or mangrove wood are ideal for structuring the aquarium. There should only be a slight current.

planting

The aquarium should be planted densely. Both fine-leaved and broad-leaved plants should be used. As already mentioned, floating plants are suitable to create some shady places. In addition to dense planting in places, there should be enough free swimming space.

Tankmates

Rummy nose tetra is peaceful and sociable fish. They are well suited for socialization with other, similarly large ornamental fish from South America. The socialization with discus fish and angelfish can lead to the rummy nose tetra feeling insecure and startled. Smaller cichlids, barblings, armored catfish or other small and medium-sized tetra species are better suited.

Likelihood of confusion

There are several types of the redhead tetra and rummy nose tetra that look very similar. The “hemigrammus bleheri” is the most popular in the aquarium hobby. The species rummy nosetetra ( Hemigrammus rhodostomus) and false rummy-nosetetra ( Hemigrammus georgiae ) look very similar to the Belehers red head tetra, but are somewhat paler and rarely found in aquariums. The keeping and care of the three species do not differ.

Reproduction

Rummy nosetetra is open breeders. Reproduction is only possible in a specially set up spawning tank. In the community basin, the probability of successful reproduction is almost zero.

Since rummy-nosetetra are spawning predators, a spawning grid in the spawning tank is helpful. A lot of patience is required for breeding rummy nose tetras, as they spawn rarely and only at certain water values—the eggs hatch after 20 to 30 hours. After about a week, the fry can swim freely. Artemia nauplii or small-grated flake food are used as rearing food.
