Maze Brain Corals
Maze Brain Corals as one might imagine get their name from their appearance. They form a dome of maze-like ridges that resemble a human brain when they get larger. They are a hardy large polyp stony coral however it is important to pay attention to placement of maze brains because they are aggressive with their sweeper tentacles. Some species of these brains can extend their sweeper tentacles 12 inches to harass neighboring corals.
