🧰Accessories for a Neon tetra: tests, upkeep and budget

Neon tetra : A moderate-flow filter, a 50 to 100 W heater, GH/KH hardness tests and possibly RO water for softening. Expect 100 to 180 euros to equip an 80 L tank.

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.

Water tests: your dashboard

A drop-test kit (€15-30) is THE first accessory for a Neon tetra tank: NO2 and NO3 weekly, GH-KH-pH at any doubt. Then come the net sized for 4 cm, the substrate siphon and the dedicated bucket — never the cleaning one, whose detergent traces contaminate the water.

a battery backup air pump: at full stocking, a filtration failure is measured in hours.

The full budget, no surprises

An equipped 60 L setup (tank, filter, heater, lighting, substrate, decor, tests): expect €200 to 450 upfront, then €10 to 25 a month (food, electricity, conditioner). Second-hand often halves the tank price — only the filter and heater deserve to be new. Details on the full Neon tetra profile.
