Tank Requirements for Black Neon Tetra 3-3.5cm
Black Neon Tetra 3-3.5cm are small, active schooling fish that appreciate:
- Tank size: from at least 2ft+ for a small group, larger is better for bigger shoals

Keeping Black Neon Tetras in a group of at least 6–8 (more if space allows) helps reduce stress and encourages natural schooling behaviour.
