Toxic Green Maze Fragment
The Toxic Green Maze Fragment is a hardy and eye-catching LPS coral that adds bold colour, texture, and structure to a reef aquarium. Also known as a Maze Coral or Brain Coral, Platygyra is recognised for its distinctive maze-like pattern made up of long, interconnected valleys and raised ridges.
This toxic green variety stands out beautifully under reef lighting, making it a great choice for reef keepers wanting a bright, textured coral for the lower to middle areas of the tank. As it grows, it slowly encrusts over the rockwork, creating a natural-looking reef structure with strong visual impact.
Toxic Green Maze Corals are generally resilient when kept in stable conditions, but they are not peaceful neighbours. Like many brain corals, they require stable water parameters and adequate lighting to thrive.

The Toxic Green Maze Fragment adds a striking visual element to my reef tank. It has grown steadily over three months and maintains its vibrant green color under proper lighting. I keep it in the middle zone with good water flow and it’s not aggressive with other corals.

It’s a beautiful coral with a unique maze-like structure. I noticed it grows slowly but consistently. I make sure to maintain stable water parameters and provide strong lighting. It’s worth the investment for reef aesthetics.

The coral arrived healthy and looks good in the tank. It hasn’t grown much yet, but I’m patient. I’m monitoring water parameters closely. It’s not as active as some other corals, but it’s still a nice addition.
