A Nano Reef is an aquarium of 30 gallons or less that gives you the opportunity to experience and learn about corals on a smaller budget than larger aquarium yet provides the same serene effect. Generally several corals, a few small fish (Nemos and Dorys, if you like), a sea anemone, some crabs and snails, and a shrimp or two would be adequate. Suitable for a desktop, countertop or stand, a Nano Reef will keep children and adults fascinated by its colorful and calming beauty while learning about our oceans species. Nano Reefs have become quite popular to aquarium hobbyists in recent years. They are fairly easy to maintain and offer a unique perspective to reef keeping.
