  • Saltwater Fish for sale

    Marine fish are some of the best additions you can make to your saltwater aquarium. Many marine fish are sought after for their bright colors, vivid patterns and spunky personalities.

    At Salty Underground we have a wide variety of saltwater fish for sale, including reef-safe saltwater fish and predatory saltwater fish.  We have several articles about marine fish for sale here.

    We do not dropship our saltwater fish from wholesalers nor do we pass them on to you, our customer, immediately after arrival. Our saltwater fish are inspected for disease, color, injuries, and behavior upon arrival. Afterward, they are acclimated and placed in a recovery system or quarantine tanks depending on need. We quarantine all of our saltwater fish for at least 7 days and if not showing any signs of disease and are eating properly we move them to a long-term holding system and listed for sale.

  • Sea Anemones

    Although it is a member of the invertebrate family, order Actiniaria - Class Anthozoa - phylum Cnidaria, the sea anemone is in a class of its own. It fills a unique niche in the home saltwater aquarium.

  • Coral

    Salty Underground brings you the highest quality live corals for sale. We have many LPS, soft corals, rare corals, coral frags and the very colorful SPS corals for sale. Also available are aquacultured corals, which are more often hardier and more successful in the home reef aquariums. Since these live corals are aquacultured corals, they have no impact on our natural reef systems around the world.

    Many of our corals for sale are WYSIWYG. This stands for "What You See Is What You Get". If you purchase one of these live corals for sale, you will receive the actual coral for sale in the photo. For those corals that do not say WYSIWYG, the photos are representative of the species, size and color of the coral for sale you will receive. This is most common when we have a great deal of the same live coral. In most cases the corals for sale in the photo and the coral you buy and are from the same mother coral colony. Read the item description for the size of the coral for sale and more information on how to care for that live coral.

  • Marine Invertebrates

    Every saltwater aquarium needs a variety of marine invertebrates to complete its natural biodiversity. Marine invertebrates provide an important function in keeping algae under control and eating excess food.

    Macro Algae and plants improve the water quality of your marine aquarium by absorbing nitrates, phosphates, carbon dioxide, and some metals. It also adds a natural biodiversity to your saltwater aquarium while serving as a food source for many marine species! Please see this article for more information about how algae can affect your aquarium.
