Custom Biota Acclimation Box – PNWCustom
Can ship with your fish order! Choose ground shipping if purchasing separately, or if you want to add this to your fish order.
An acclimation box is the best tool for introducing new fish to established fish in your tank or for introducing fish to one another for pairing/breeding purposes. New fish tend to hide when first introduced to an aquarium and can be more difficult to feed. Keeping them in an acclimation box on arrival allows you to keep a close eye on them and ensures the food you’re giving them is well within their reach. Give your fish a chance to rest and recuperate after shipping with a comfortable acclimation box.
Also great for anemones and corals like mushrooms that need a low flow area to attach to substrates without being swept away by the current.

The acclimation box arrived quickly and is perfectly sized for my tank. My new fish stayed calm and ate well during the transition. It’s a simple but effective tool that made the process much easier.

I used it for introducing two new angelfish. The box kept them safe and allowed me to monitor their behavior. The low flow is ideal for the anemones I have as well.

Great product for beginners. My first time adding fish to the tank, and the box helped me avoid stress. The fish were active and eating within hours of arrival.
