How to Care for Soft Corals

The term "soft corals" refers to the phylum Cnidaria, which includes stinging corals such as jellyfish, sea-pens, and anemones. Soft corals are distinguished by their internal soft skeletons, which do not produce calcium carbonate found in other hard corals. As such, they are not reef-building coral. Soft corals are easily collected in the wild for reef aquarium hobbyists, but also grow quickly in captivity. Dividing and aquafarming soft corals in captivity is an environmentally conscious way to enjoy their beauty. Most soft corals appropriate for individuals are found in shallow waters. Proper care primarily involves understanding the needs of the particular species.

Instructions

    • 1

      Investigate the type of soft coral most appropriate for your aquarium. If soft coral is already present in your tank, finding reference information on the type of coral will help ensure its health.

    • 2

      Supplement your reef system. For example, sea fan soft corals require calcium, iodine, and strontium supplementation for proper growth. Make certain the supplements for one group of soft corals do not interfere with the health of other groups within your aquarium. Not all corals require the same minerals.

    • 3

      Maintain optimal tank conditions. Frequently check and maintain the appropriate temperature and pH levels in your coral system. Sea plume soft coral, for example, requires a temperature range of 72 to 78 degrees Fahrenheit and a pH of 8.1 to 8.4.

    • 4

      Light the tank appropriately. Many soft corals rely on photosynthesis for part of their food production, and improper lighting hampers that function. Adjust the lighting based on the groupings of coral present, as some species require bright constant light while others flourish in shady conditions.

    • 5

      Create suitable water flow conditions. Corals are essentially non-mobile, so create an environment that actively provides nutrients and supplements. For example, mushroom or leather soft coral requires medium water flow while devil's hand coral needs a strong water flow.

      Establish equilibrium in your aquarium. Work to build a constant, unchanging environment. Introduce new species carefully and over time.
