Rummynose Tetra 3.5cm (Group of 10)

The Rummynose Tetra (Hemigrammus rhodostomus) is one of the most prized schooling fish in the freshwater hobby, instantly recognisable by its vivid red nose, silver body, and bold black-and-white striped tail. Famous for their tight, synchronised schooling behaviour, a group of Rummynose Tetras moving as one through a planted aquarium is a truly mesmerising sight. They are a benchmark species for well-maintained, mature aquariums.

Care Guide

• Tank Size: Minimum 80L; best kept in schools of 10 or more — larger schools produce the most impressive shoaling behaviour
• Water Parameters: pH 5.5–7.0 | Temp 24–28°C | Soft, slightly acidic water strongly preferred; sensitive to poor water quality
• Diet: Omnivorous — quality micro pellets and flake food; supplement with frozen or live daphnia, brine shrimp, and micro worms
• Temperament: Peaceful; ideal community fish — avoid housing with large or aggressive fish
• Tank Setup: Densely planted aquarium with open swimming space; dark substrate and tannin-stained water enhances their vivid red colouration and encourages tight schooling
• Skill Level: Intermediate — requires stable, well-maintained water parameters
• Max Size: 5cm
