30-Day Saltwater Fish Quarantine Protocol to Prevent Ich and Velvet

Quarantining new saltwater fish is the single most reliable way to protect your display reef from parasites like ich and velvet. This guide gives you a practical 30-day protocol that works for beginners and experienced reefers.

Why quarantine matters in every reef tank

Every fish can carry pathogens even when it looks healthy at purchase. A simple quarantine system gives you a safe place to observe behavior, stabilize feeding, and treat preventable issues before the fish enters your display. Practical tip 1: use your ReefBay notes and parameter history to document appetite, respiration, and behavior changes each day so decisions are based on trends, not guesses.

QT tank setup checklist

Use a bare-bottom tank, heater, lid, sponge filter, PVC hiding pieces, and a reliable ammonia alert badge. Keep salinity and temperature close to the source water, then match your display over several days.

Water quality targets during quarantine

Keep temperature 77 to 79F, salinity stable, ammonia at zero, nitrite near zero, and nitrate controlled with water changes. Stable parameters reduce stress and improve immune response.

Day 1 to 3: Acclimation and feeding

Prioritize calm acclimation, dim light, and easy foods like frozen mysis or enriched brine. Track appetite and breathing rate. Fish that eat early generally quarantine more successfully.

Day 4 to 14: Observation and early intervention

Look for flashing, spots, frayed fins, excess mucus, heavy breathing, and white film. Isolate symptoms early. If issues appear, start treatment in QT instead of risking your reef display.

Day 25 to 30: Final stabilization before transfer

Ensure fish are active, eating consistently, and symptom-free. Match salinity and temperature to display tank over 48 to 72 hours to reduce transfer stress.

Common quarantine mistakes to avoid

Overcrowding QT tanks, skipping test kits, overfeeding, and rushing transfers are the most common causes of failure. Slow, consistent process beats shortcuts every time.

What to do after quarantine

Add fish with lights dimmed, observe social behavior, and feed lightly at first. Keep a simple log for the first week in display to catch stress signs early.
