🎾Enriching a Neon tetra tank: hardscape, shoal and occupation
Neon tetra : An Amazon-style setup: dense planting around the edges, driftwood roots and a few dead leaves that amber the water. A dark substrate and soft lighting bring out its colors.
In short: 3 to 4 cm as an adult, 60 to 80 L minimum for a school of 10, soft water between 21 and 25 °C. Gregarious and timid, it only settles in a tight school of ten or more, otherwise it pales and hides. A small tetra sensitive to osmotic shock: keep it only in a mature tank, in soft, slightly acidic water with subdued lighting.
Hardscape designed for its swimming zone
The swimming zone dictates the decor: a Neon tetra moves in midwater, so tall background plants, wood and clear swimming lanes organise its space. An aquarium’s enrichment is its hiding places and its currents — not fluorescent ornaments.
Group life: the first enrichment
From 10 individuals up, the Neon tetra becomes itself again: hierarchies settling, displays, coordinated swimming — in small numbers it lives in chronic stress and loses its colours — group size is the species’ first “toy”, before any decor purchase.
Food as occupation
Feeding is occupation lever number one: prey in the current, multiple shifting feeding points — the underwater equivalent of a mammal’s snuffle mat.
Frequently asked questions
How many Neon tetra should be kept together?
10 minimum, more if the tank allows: it is a shoaling species, and numbers shape its behaviour and colours alike.
How do you enrich a Neon tetra tank?
Through layout above all: decor designed for its living zone (in midwater), meals served in varied ways and a complete group — gadgets add nothing.
