Large Cactus Coral

About

Large cactus coral (Mycetophyllia lamarckiana) is a stony coral native to the Western Atlantic, ranging across the Gulf of Mexico, the Caribbean Sea, and as far as Bermuda. In the wild it grows as a solid, flattened to rounded plate, with broad, shallow valleys that radiate outward from the original growth point in a roughly concentric pattern. Each valley contains a single row of mouths, giving the surface that characteristic ridged, almost sculpted look that earns this genus its cactus coral nickname. Coloration tends toward muted tones. Mottled greys and browns are typical, though some individuals show a touch of green depending on their zooxanthellae. Wild colonies are found across a wide depth range, turning up in most reef environments from shallow water down to around 58 meters. In the aquarium this coral is considered a reasonable choice for newer reef keepers, tolerating moderate light and flow without demanding precision conditions. It is reef safe and poses no particular threat to neighbors when given adequate space. Overall it is a low-drama addition to an Atlantic-themed system or any mixed reef where you want some bottom-level texture and a piece of genuine Caribbean character.
