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
Décor: planted tanks with open swimming space and some shaded areas
Filtration: gentle to moderate flow with good biological filtration
Substrate: sand or fine gravel, with plants, wood and leaf litter for a natural look

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

Water Parameters (Guide Only)

Black Neon Tetras are relatively hardy and adapt well if changes are slow:

Temperature: around 23–27°C
pH: roughly 6.0–7.5
Hardness: soft to moderately hard water
Ammonia & Nitrite: 0 ppm
Nitrate: kept low with regular water changes

Stable, clean water and a mature filter are more important than chasing exact numbers for your Black Neon Tetra 3-3.5cm.

Feeding Black Neon Tetra

The Black Neon Tetra 3-3.5cm is an omnivore and enjoys a varied diet:

Quality micro pellets or fine flakes designed for small tropical fish
Frozen or live foods such as baby brine shrimp, daphnia and finely chopped bloodworms
Occasional vegetable‑based or spirulina‑rich foods

Feeding small amounts 1–2 times per day keeps your Black Neon Tetras active, colourful and in good condition.

Behaviour and Tank Mates

Black Neon Tetras are peaceful schooling fish that do very well in community aquariums:

Behaviour: active mid‑water swimmers that feel safest in a group
Temperament: peaceful, ideal for calm community setups
Best kept: in shoals of at least 6–8 Black Neon Tetras

Suitable tank mates include other small peaceful tetras, rasboras, Corydoras, small peaceful catfish and dwarf cichlids, as well as many community‑safe invertebrates. Avoid large or aggressive fish that may see Black Neon Tetra 3-3.5cm as food.

Important Notes

Always introduce Black Neon Tetra 3-3.5cm to a mature, cycled aquarium.
Keep them in groups for best colour, confidence and natural schooling behaviour.
Regular maintenance and good filtration help keep this species healthy long‑term.
