The Rhodactis Bullseye Mushroom is also known as the Tonga Blue Mushroom and is less commonly referred to as a Hairy or Small Elephant Ear Mushroom. The Bullseye Mushroom usually is a violet to blue color, often with margins and highlights of green and may have a red mouth area, with papillae that form cauliflower-like patterns, and can grow up to 3 inches in diameter. This is a relatively easy species to care for and can thrive with lower lighting and waterflow. The Bullseye Mushroom makes a good coral for beginner reef aquarists in that it is relatively easy to care for and is a very attractive specimen.

It is very easy to maintain the Bullseye Mushroom in the reef aquarium, mostly because it prefers low to medium lighting and low water movement. The Bullseye Mushroom is less tolerant of bright light compared to other Rhodactis sp., prefering reduced lighting, which normally requires that is be placed in the lower regions of the aquarium or where it is partially shaded. It is a semi-aggressive species and requires adequate space between itself and other corals so as not to damage any nearby neighbors. Longitudinal fission is the primary means of reproduction and it normally is sold as several individual mushrooms attached to one rock.

The Bullseye Mushroom Coral receives most of its nutrition requirements through the symbiotic algae zooxanthellae hosted within its body through photosynthesis, which provide the majority of its nutrition. It may also eat plankton and small invertebrates which can be provided through supplemental liquid foods.
