Sustainable Aquatics will be at BAYMAC. They have a very intense selection of Captive Bred and Captive Reared(raised). Currently they are the only ones offering captive reared Pac Blue Tangs and Yellow Tangs.
Captive Reared is when they get the fish at a super super small size, not larval, and tank rear them until they are of size for a hobbyist to take care of.
