🧴Care and grooming for your fish: the gear that matters

Brushes, hygiene products, parasite control, habitat upkeep: your fish’s routine care happens at home, with the right equipment. Our guides separate the essential from the gimmick — and say when the vet, not the shop aisle, should have the answer.

The key point : A test kit (NO2, NO3, GH, KH, pH) costs €15–30 and prevents most disasters — the nitrogen cycle is non-negotiable.
