Frequently Asked Questions

A minimum of 14 days is recommended, with 21 days preferred. This allows time for latent parasites and bacterial infections to manifest. Some experienced keepers quarantine for 30 days, especially with imported fish.

Keep quarantine tanks between 72-78 degrees F (22-26 degrees C). Warmer water speeds up parasite life cycles, making them easier to detect and treat. Avoid temperatures below 65 degrees F during quarantine.

Yes, a cycled biological filter is critical. Ammonia and nitrite spikes during quarantine can stress or kill fish. If your filter is not cycled, plan for daily water changes and careful ammonia monitoring.

Use dedicated nets and equipment, a current water test kit, reliable aeration and filtration, and a conditioner appropriate for your water source. Ask a qualified aquatic veterinarian before selecting any medical treatment.

Fish from the same source and shipment can generally be quarantined together. Never mix fish from different sources in the same quarantine tank, as they may carry different pathogens.
