Natural habitat

Rummy Nose Tetras originate from the blackwater regions of the Rio Orinoco in Venezuela and the lower Amazon Basin in Brazil. They thrive in soft, acidic waters rich in humic acids from decomposing leaf litter, with habitats featuring rocks, caves, and dense vegetation that provide ample shading and food sources.

Where they are found

Often found in groups, these fish have a strong schooling behavior. Their schooling nature and peaceful temperament make them excellent additions to community tanks with similar sized and temperamented species.

Aquarium care

Regular testing and maintenance are essential for Rummy Nose Tetras as they are sensitive to water parameters like pH and hardness. A well-cycled tank with a soft substrate and plenty of swimming space is ideal. Weekly water changes are recommended to prevent stress and ensure a stable environment.

Feeding

A balanced diet should include high-quality flakes or pellets, supplemented with occasional treats such as bloodworms, daphnia, and finely chopped green vegetables to cater to their omnivorous diet and enhance their overall health.

Compatibility

Rummy Nose Tetras are peaceful and best housed with other small, non-aggressive fish. They typically coexist well with Danios, Rasboras, and other Tetra species, while avoiding cichlids or aggressive fish that may stress them.

Breeding

Breeding Rummy nose tetras can be done in a separate breeding tank with soft, slightly acidic water. They are egg scatterers, laying their eggs among fine-leaved plants or spawning mops. Eggs typically hatch within 24 to 36 hours, and fry should be fed infusoria until they can accept larger foods.
