Red Gorgonian Not a Good Tank Inhabitant
While red gorgonian coral are popular choices to be placed in reef tanks and aquariums, they are more difficult to take care of versus other soft corals, as the red Red Gorgonian Culturegorgonian is very particular when it comes to lighting access and water movement
The red gorgonian should be placed at the very bottom of the tank, within close proximity to where the water gushes in from the filter. Many aqua culturists find canister filters to work the best for this type of coral, as the head can be manipulated in the exact direction of the red gorgonian. The water quality should consist of a steady temperature between 72 and 76F and salinity between 1.022 to 1.026. Lighting is one of the most important elements in keeping the red gorgonian alive, as this coral will need access to light 6 hours per day (make sure the light is set on a timer, as exposing more light than required can increase the temperature of the tank and contribute to an algae infection.)
