20 × Neon Tetras (Paracheirodon innesi) – Captive Bred

This listing supplies a group of 20 captive-bred Neon Tetras (Paracheirodon innesi). Plan the aquarium for the whole group as it grows, together with any existing tank mates.

Neon Tetras are peaceful schooling fish; a shoal of 20 turns a planted tank into a moving ribbon of blue and red.

The Neon Tetra, Paracheirodon innesi, is the classic small shoaling fish for peaceful planted aquariums. Its bright blue stripe and red lower body give a mature community tank instant movement and colour without adding aggression. This listing is specifically for captive-bred Neon Tetra, Paracheirodon innesi.

Neon Tetras are best kept in groups of 10 or more. A proper shoal helps them feel secure, improves colour, and gives the calm coordinated swimming behaviour people buy them for. They suit peaceful tank mates such as small rasboras, ember tetras, corydoras, otocinclus, dwarf gourami, cherry shrimp in established tanks, and other gentle community fish. Avoid large predatory fish, fin nippers, and boisterous cichlids.

Neon Tetra care and tank setup

Use a mature aquarium with gentle filtration, steady heating, and plenty of plant cover. Darker substrate, driftwood, floating plants, and shaded areas help Neon Tetras settle and show stronger colour. Leave open midwater swimming space so the whole group can move naturally. Choose the tank around the adult shoal, the other inhabitants and the capacity of its filtration; a planted layout should still leave an open swimming area.

They are small fish, but they still need stability. Avoid adding a full group to a brand new tank. Keep ammonia and nitrite at zero, keep nitrate low with regular water changes, and acclimatise slowly when the fish arrive. A stable planted tank is far more important than chasing an exact pH number.
