The beauty of the Bullseye Mushroom or Tonga Blue Mushroom makes it one of the most striking of the Elephant Ear Corals. It has a very colorful appearance, with tentacles that are more like clusters than individual single tentacles.
The various colors within their body include purple, with green margins and highlights as well as multicolored green, red, and blue with some having a red mouth. These contrasting colors are found in the tentacles, tentacle tips, mouth and body color. The area around the oral disc is bare, thus making it an easy species to identify.
The Bull's Eye Mushroom does not pose a threat to your fish like other Rhodactis, making it great for a great nano tank that has small fish. Only getting to a maximum of 3" (8 cm) makes this Rhodactis a favorite for those who have smaller quarters and who need a less demanding mushroom.
The Rhodactis inchoata is easy to care for but only likes dim to moderate light. If the lighting is not their liking, they will fail to thrive and/or shrink. They can easily be brought back by changing their position in the water and by extra feedings. As far as water movement, they cannot handle high water flow, and prefer low velocities. They can be fed small particles of foods like Cyclo-peeze, daphnia and may occasionally accept very small pieces of fish and crustacean flesh. They are not as needy as other Rhodactis species when it comes to regular feedings.
The R. inchoata is easy to propagate in any home aquaria, which can contribute to preserving the wild populations. Just keeping it well fed with small pieces of fish and crustaceans will cause the it to multiply quickly. Even after splitting, the clone mushroom at times doesn't always resemble the "mother" mushroom. Predators are unknown.
