How long do Rummy-nose Tetras live?
In clean, stable water they live about 5-6 years. Stress from fluctuating parameters shortens that considerably, so consistency is the key to a long-lived school.
What do Rummy-nose Tetras eat?
They accept small flake, micro-pellets and frozen/live foods like brine shrimp and daphnia. The mistake is overfeeding and one-food diets; keep portions small and varied, finished in two minutes.
Tank size and water parameters
A 20-gallon (75 L) tank or larger suits a school of 8-12. Target 75-84°F (24-29°C), pH 6.0-7.0, soft water, zero ammonia and nitrite, nitrate under 20 ppm. Keep in groups of 6+; strong filtration and regular water changes keep the nose bright.
Common mistakes with Rummy-nose Tetras
Top errors: unstable water and ammonia spikes (they are sensitive); too small a group so they never school; and adding them to a new tank — they belong in a mature, stable system where their color stays vivid.
Beginner mistakes to avoid
- Unstable or dirty water — rummy-noses are sensitive and their color is the first to suffer.
- A small or shy group — they need 6+ to form the tight school that defines them.
- New, uncycled tanks — place them only in mature, well-filtered aquariums.
- Overfeeding and flake-only diets — small varied portions protect water quality.
