“Slow Drip, Stress-Free” Method For Saltwater and Freshwater Fish

            ⚠️ Attention Customers:
        coralSLover® fish come from trusted sources:

  • Saltwater fish arrive directly from the wholesaler in natural ocean water, which has lower salinity and different conditions than your aquarium. This water is not like the controlled conditions in a home tank. If fish are not properly acclimated, they may die.

  • Freshwater CaptivFish® and Saltwater CaptivFish® species are typically shipped in water with slightly different parameters than your home aquarium. Improper acclimation can cause stress, disease, or death.

  • Freshwater fish (imported fish) often come from water conditions very different from your aquarium. These fish require the Slow Drip, Stress-Free Method, the same acclimation process recommended for saltwater species. Following these acclimation steps carefully is essential for the health and survival of your new fish.

Purpose:

Gradually adjusting your fish to your aquarium’s water parameters (temperature, salinity, pH) ensures they thrive in your tank without shock or stress.

coralSLover® Recommendation

  • Always acclimate in a separate container, not directly in the aquarium.

  • Delicate or wild-caught species may require longer drip times.

  • Keep lights low and minimize disturbances during acclimation.

    You’ll Need

  • A clean bucket or container

  • Airline tubing or small siphon

  • Clamp or knot to control drip rate

  • Timer or watch

  • Step 1: Float & Match Temperature

  • Float the sealed shipping bag in your aquarium for 10–15 minutes.

  • This allows the fish to gradually adjust to your tank’s temperature.

  • Step 2: Prepare the Drip Setup

  • Transfer your fish into a clean bucket with water from the shipping bag.

  • Start a siphon using airline tubing from your aquarium to the bucket.

  • Adjust the drip to 1 drop per second (~2–4 mL/min).

  • Step 3: Slow Drip Acclimation

  • Slowly add aquarium water to the bucket over time.

  • Goal: Double the bucket volume gradually over 1–3 hours, depending on fish sensitivity.

  • Important: Monitor fish closely. Signs of stress include clamped fins, rapid swimming, or gasping.

  • This process allows your fish to adjust to higher salinity and aquarium conditions safely.

  • Step 4: Transfer to Aquarium

  • Once fully acclimated, gently net the fish into the tank.

  • Do not pour bucket water into the aquarium—this protects your tank from possible contaminants.

  • Step 5: Post-Acclimation Care

  • Observe your fish for 24–48 hours.

  • Avoid feeding immediately; let your fish settle into their new environment first.

Freshwater CaptivFish®

Float the Bag

  • Float the sealed bag in your aquarium for 5–10 minutes to match tank temperature.

Gradual Water Addition

  • Total acclimation time: 15–30 minutes, depending on sensitivity.

Transfer

  • Gently net the fish into the tank.

  • Do not pour bag water into the aquarium.

Observation

  • Monitor for stress: hiding, clamped fins, or unusual behavior.

  • Provide hiding spots if needed.

Saltwater CaptivFish®

Float the Bag

  • Float the sealed bag in your saltwater aquarium for 5–10 minutes to match tank temperature.

Gradual Water Addition

  • Slowly add small amounts of aquarium water to the bag every 2–5 minutes.

  • For delicate or sensitive species, consider using the Slow Drip, Stress-Free Method instead.

Transfer

  • Gently net the fish into the tank.

  • Avoid pouring bag water into the aquarium.

Observation

  • Monitor for stress: clamped fins, rapid swimming, or gasping.

  • Provide hiding spots and keep lights low during the first 24 hours.
