ACCLIMATING FISH - Do not float breathable bags in your aquariums
Do not float breathable bags in your aquariums. The bag will no longer breath when immersed in water and the fish may actually suffocate. Also as the temperature inside the bag rises so does the ammonia level. Ammonia levels of just .02 ppm could harm or even kill your new fish. It is better to gently pour fish and water to a plastic container. Slowly add aquarium water to acclimate the fish. When the fish are acclimated to the water and temperature of their new tank, net the fish and transfer them to the aquarium. Discard acclimating water. Never add shipping or acclimating water to your tanks. You could be adding contaminants and unwanted guests. Keep fish in the dark until they get accustomed to their new surroundings. Don’t worry about feeding your new fish for at least 3 hours.
