Rummy nose tetras (Hemigrammus rhodostomus) are generally considered hardy fish when kept in suitable conditions. They are adaptable to a wide range of water parameters and are not particularly sensitive compared to some other species. However, like all fish, they do have specific requirements to thrive:
- Water Quality: Rummy nose tetras prefer clean, well-oxygenated water. Regular water changes and proper filtration are essential to maintain good water quality.
- Temperature and pH: They prefer slightly acidic to neutral water with a pH range of around 6.0 to 7.0 and a temperature between 75-82°F (24-28°C). Stability in these parameters is crucial for their well-being.
- Tank Mates: They are peaceful fish and do well in community tanks with other peaceful species. However, avoid housing them with aggressive or large fish that may intimidate or harass them.
- Tank Size: A larger tank with plenty of swimming space is ideal for rummy nose tetras. A minimum tank size of 20 gallons is recommended for a small school.
- Diet: They are omnivores and will accept a variety of foods including high-quality flake food, live or frozen foods like bloodworms and brine shrimp, and occasionally vegetable matter.
- Schooling Behavior: Rummy nose tetras are shoaling fish and should be kept in groups of at least six individuals. Keeping them in smaller groups can cause stress and lead to health issues.
Overall, with proper care and attention to their requirements, rummy nose tetras can be hardy and rewarding fish to keep in a community aquarium.
