Lettuce Coral

About

Lettuce coral (Pectinia lactuca) earns its common name from the way its colonies form broad, plate-like or submassive structures covered in long, winding valleys and ridges that do look a bit like a crinkled leaf of romaine. Colonies can grow impressively large in the wild, regularly exceeding a metre across, with valleys that tend to run continuously from the center of the colony out to its edges. A useful identification feature. Coloration is generally understated: greys, browns, and muted greens are the norm, so this isn't a coral you're keeping for bold color. What makes it interesting is its adaptability. Across the Indo-Pacific, it shows up in a wide range of reef conditions, and it's particularly at home on lower reef slopes and in turbid, lower-clarity water where more demanding corals wouldn't fare as well. That resilience carries over into the aquarium to a degree. It tolerates moderate flow and moderate lighting without much fuss, though it still deserves the attention of a keeper who understands reef water chemistry basics. It's not a beginner's coral, but for someone with a stable system looking to add some textural variety, lettuce coral is a solid, dependable choice.
