The biorb air pump is what pumps the oxygen into your biorb and biube aquarium. There are two sizes, one for the baby biorb aquarium, and another for all other sizes of biorb, biube, or biorb life tanks.
HAVE A BETTA IN YOUR BIORB? HERE’S A TIP
If you have a betta in your biorb aquarium sometimes the air flow from the biorb or baby biorb air pump is too strong for betta fish and can make it hard for your fish to stay at the top of the aquarium. If you are noticing that problem try attaching a small clamp or clip to the air tube coming from the air pump to slow down the air flow. Once the air flow has slowed down from your pump your betta fish will be be able to stay at the top of the aquarium longer.
