In the interest of healthier, better-acclimated fish and also because we want to do our part in preserving the world’s reefs, Pets Plus also carries a wide selection of aquacultured and tank-raised saltwater fish. These fish are 100% bred and raised in captivity and offer numerous environmental benefits over wild-caught fish. We now work with several aquaculture facilities and our selection of tank-raised fish is constantly growing!
