  • Saltwater Fish for sale

    Salty Underground features an ever growing selection of saltwater fish. Marine fish add color and activity to the reef aquarium. Saltwater fish also tend to occupy different levels in the water column and areas of the aquarium. Some fish will perch on live rock while others will be in the middle, front and center! When picking out fish it is good to consider this aspect in order to have a balanced look. Find out more about saltwater fish here.

    Check back often as new marine fish are added regularly!

    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.

  • Sea Sponge

    Sea sponges come in a variety of colors and shapes. Sponges depend on water flow to bring them food. They are filter feeders and do best in well established aquariums, with clean water that has high nutrient level from which to feed.

  • 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.

  • Marine Macro Algae

    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.
