What do Acanthastrea Corals look like: The A. echinata has corallites (skeleton formation under each polyp) that have even walls, height wise, so there is a more uniform appearance to the coral. Inspecting the polyps of the A. echinata when not fully expanded reveals that these walls are being shared, thus contributing to the identification. When the polyps retract, due to their fleshy polyps, little folds appear almost like an accordion. They come in rust, brown and green, but captive frags can have lavenders (gray), orange (rust), and bright green combinations. The Acan Echinata Acanthastrea echinata is a colorful large polyp stony (LPS) coral in the Mussidae family. They are found in some intense oranges to intense green and red combinations.The Echinata Coral is the second most popular and sought after of the Acanthastrea species, following the Acan Lord A. lordhowensis. Some descriptive names the A. echinata are known by include Echinata Coral, Starry Cup Coral, Artichoke Coral, Pineapple coral, Rainbow Acanthastrea, Rainbow Acan, and Acan Brain Coral. Medium, do not use metal halide. As for flow and placement, there are a couple of things I look for. Micromussa do not require a ton of flow, so I look to provide just enough so detritus does not settle on them. Most of the time hobbyists place Micros towards the bottom of the tank so it is important that they get enough flow to keep them clean. On the other hand, I think feeding is important for long term health so preferably the flow can slowed during feeding time to allow the coral to grab pieces out of the water column. Acanthastrea Coral Feeding: The Acanthastrea genus, like other large polyp stony (LPS) corals, have developed several feeding strategies. Through a symbiotic relationship with a marine algae, known as zooxanthellae, they receive some of their nutrients. They also capture planktonic organisms, food particles from the water column, and can absorb dissolved organic matter. Frags up to 1" size.
