🧰Accessories for a Guppy: tests, upkeep and budget
Guppy : A standard filter, a 50 to 100 W heater, a fine net for fry and possibly a breeding box. Equipment budget of around 80 to 150 euros for a 60 to 100 L tank.
In short: 3 to 6 cm as an adult depending on sex, 60 L minimum for a group, water between 22 and 26 °C. Peaceful and sociable, yet males court relentlessly: keep two to three females per male to spread the pressure. An ultra-prolific livebearer in hard alkaline water: plan for overpopulation and avoid the very soft acidic water that weakens it.
Water tests: your dashboard
The first smart buy for a Guppy costs €15 to 30: the drop-test kit, out weekly for NO2-NO3 and at any doubt for GH, KH and pH. Then come the net sized for 6 cm, the substrate siphon and the dedicated bucket — never the cleaning one, whose detergent traces contaminate the water.
The Guppy specifics
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 Guppy profile.
