Hemigrammus rhodostomus (Rummy Nose Tetra)

Background:

The Rummy Nose Tetra, Hemigrammus rhodostomus, is a strikingly beautiful freshwater fish originating from the slow-moving rivers of the Amazon Basin in South America. Its distinctive bright red snout, contrasting with a silver body and black-and-white striped tail, makes it a popular choice among aquarists. Known for its tightly schooling behavior and peaceful nature, this species is ideal for creating dynamic displays in planted community tanks.

Care Requirements:

• Water Parameters:

  • Temperature: 23–27°C
  • pH Range: 5.5–7.0
  • Hardness: 2–10 dGH

• Diet:
  Rummy Nose Tetras are omnivorous and thrive on a varied diet of high-quality flakes, micro-pellets, and frozen or live foods such as daphnia, bloodworms, and brine shrimp. Feed small portions 1–2 times daily to match their grazing habits.

• Tank Setup:
  A minimum tank size of 60 liters is recommended for a school of at least 6–8 individuals. Use a soft sand or fine-gravel substrate and densely plant the tank with species like java fern, Amazon swords, or cryptocorynes to mimic their natural habitat. Driftwood and leaf litter can add tannins, softening the water and creating the subdued lighting they prefer. Gentle filtration and a slight current will simulate their native conditions.

• Behavior:
  Rummy Nose Tetras are highly social and should be kept in groups of at least six to exhibit their natural schooling behavior. They are peaceful, making them excellent community fish. Their schooling tendencies create a cohesive and synchronized display, particularly when swimming in open spaces.

• Tank Mates:
  Compatible tank mates include other small, peaceful species such as cardinal tetras, harlequin rasboras, dwarf cichlids, and corydoras catfish. Avoid housing them with large or aggressive fish that might view them as prey.

Care Tips:

To ensure the health and vibrancy of Rummy Nose Tetras, maintain excellent water quality through weekly water changes of 20–30% and regular filter maintenance. Their vivid red snout is a good indicator of water quality—fading coloration may signal stress or suboptimal conditions. Provide ample swimming space alongside planted areas for a balanced environment.

Rummy Nose Tetras captivate aquarists with their unique appearance, synchronized schooling, and gentle temperament. They bring elegance and harmony to community aquariums, making them a beloved choice for creating lush, peaceful aquatic displays.
