Acclimation Guide

1. Prepare Your Aquarium

Make sure your aquarium is fully cycled, with 0 ammonia and 0 nitrite, and the temperature is suitable for your new fish.

2. Start Drip Acclimation

Place your fish and their transport water into a clean container. Using airline tubing, slowly drip water from your aquarium into the container at approximately 2–4 drops per second.

3. Slowly Add Aquarium Water

Over the next 30–60 minutes, allow the water volume to approximately double. This helps your fish gradually adjust to their new water conditions.

4. Transfer Your Fish

Gently net your fish into their new aquarium. Avoid adding transport water to your tank.

5. Give Them Time to Settle

Keep the aquarium lights off for a few hours and wait until the following day before feeding.

Important: Arrived with an issue?

If any fish arrive dead (DOA), keep the transport bag sealed and contact us within 24 hours with clear photos of the fish inside the unopened bag.

See our DOA Policy for more information.

Basic Care Information: Southern Pygmy Perch are small freshwater fish that inhabit slow-moving streams, wetlands, and vegetated waterways. Provide a mature, well-planted aquarium with gentle water flow, hiding places, and stable water conditions. They prefer small live foods and may be shy when housed with larger or aggressive fish. Keep them with compatible tank mates of similar size and ensure their specific temperature requirements are met.
