How It Works

Quarantining new fish for 4 weeks before adding them to your display tank prevents disease outbreaks that could wipe out your entire stock. A bare-bottom 20-gallon tank with a sponge filter is ideal. The "quarantine trio" (antibiotic + antiparasitic + antifungal) prophylactically treats the most common diseases.
