The Moon Grouper, commonly referred to within the hobby as the Red Louti Grouper and the Lyretail Grouper, is a large, vividly colorful and hardy species that can be found among the coral reefs throughout the tropical Indo-Pacific and the Red Sea. Moon Groupers, like their similar, Miniatus cousins, are also one of the most colorful groupers within the hobby and can be identified by their intense base coloration of bright red to orange, covered by a multitude of pink to purple spots; they also have bright yellow at the rear sections of all their fins. The yellow marking on their caudal fin resembles a crescent moon, which is how they initially earned the names of "Moon" and "Lyretail". Moon Groupers have strong, pharyngeal teeth that line their throats, which they use to crush prey that are stopped in their tracks and held fast by their many sharp, curved teeth. Moon Groupers are aggressive and can become quite territorial, they should be added as the last inhabitant to their desired aquarium to ensure their tank mates have already established their territories. Moon Groupers are readily available within the hobby, from local and online retailers alike.
