Introduction

The Rummy Nose Tetra is a striking and highly popular schooling fish, instantly recognisable by its bright red-orange face and boldly striped black-and-white tail. Combined with their peaceful nature and tight schooling behaviour, they make an excellent addition to planted and nano aquariums.

Physical Characteristics

Growing to around 2.5–3.8 cm, Rummy Nose Tetras are small but visually impactful. Their vivid red facial coloration intensifies in healthy, well-maintained aquariums, while their horizontal tail striping creates a dramatic contrast and cohesive look when schooling.

Behaviour & Compatibility

Rummy Nose Tetras are peaceful schooling fish that thrive in groups of six or more, though larger groups create a more impressive display.

• Occupy the middle to upper water column

• Suitable for community tanks with other small, peaceful fish

• Can coexist with adult dwarf shrimp and larger peaceful invertebrates

• May prey on very small shrimp or fry

Their tight, synchronized schooling adds constant movement and visual interest to the aquarium.

Diet & Feeding

As omnivores, they are easy to feed and will readily accept:

• High-quality flake food

• Micro pellets

• Frozen or freeze-dried tubifex

• Bloodworms

A varied diet helps maintain vibrant colour and strong overall health.

Tank Setup & Care

Minimum Tank Size: 40L (10 gallons)
Temperature: 18–27.7°C
Preferred pH: 5.5–7.0 (slightly acidic preferred)

For best results:

• Provide a well-planted aquarium

• Include driftwood, caves, and rockwork for cover

• Add leaf litter or botanicals to create a natural, tannin-rich environment

• Maintain stable water parameters with regular water changes

Stable, clean water is essential for keeping their red coloration bright — fading colour often indicates stress or poor water quality.

Breeding

Breeding Rummy Nose Tetras is moderately challenging but achievable.

To encourage spawning:

• Use soft, acidic water

• Provide dense plants or spawning mops

• Condition adults with live and frozen foods

Eggs should be separated from adults, as they may be eaten. Fry can be raised on infusoria followed by baby brine shrimp.

Why We Like This Fish

• Striking red face and bold tail striping

Conclusion

Rummy Nose Tetras are a fantastic choice for anyone wanting colour, movement, and harmony in their aquarium. With proper care, stable water conditions, and a varied diet, they will thrive and provide a vibrant, coordinated display in any well-maintained tank.
