Saltwaterfish.com has been selling Reef Packages online since 1999. These packages were designed to help hobbyists in their selection of reef compatible invertebrates. Some packages are designed for specific aquarium sizes while others are a collection of popular reef invertebrates that we feel will make a great addition to your tank. Invertebrates are an integral part of any saltwater aquarium. They help to battle different types of algae as well as adding lots of activity and life at a very reasonable price. We highly suggest these Reef Packages for any hobbyist.
