🧰Accessories for a Danio: tests, upkeep and budget
Danio : A strong-flow filter, a lid, a quick net and an optional heater depending on the room. A modest budget of around 80 to 150 euros for an 80 to 100 L tank.
In short: 4 to 5 cm as an adult, at least 80 L and an 80 cm long tank for a school, water between 18 and 25 °C. Tireless and playful, it races against the current in a school and may harass slow, long-finned tankmates. A cool to temperate fish often kept without a heater, but demanding in length: an 80 cm tank and a lid since it jumps.
Water tests: your dashboard
A drop-test kit (€15-30) is THE first accessory for a Danio tank: NO2 and NO3 weekly, GH-KH-pH at any doubt. Complete it with a net matched to its 5 cm, a gravel siphon for maintenance and a bucket strictly reserved for the tank: residual detergent from a household bucket is poison.
The Danio specifics
a tight-fitting lid with no gaps: the species jumps, and every slot is a one-way exit; a battery backup air pump: at full stocking, a filtration failure is measured in hours.
The full budget, no surprises
An equipped 80 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 Danio profile.
