Description
You are buying the exact WYSIWYG ACI Silver Thunder Maze Goniastrea Mini Colony pictured. Its bright green maze-like ridges contrast with silver, pale blue, and white valleys under blue reef lighting.
“Maze brain” is a broad common name. This listing retains the supplier’s Goniastrea trade identification without assigning an unsupported species. Use broad indirect flow that keeps debris out of the valleys without pinning the tissue against the skeleton.
