The Platygyra Coral also called Maze Brain Coral from Australia we have here our Toxic Green Platy. An uncommon Large Polyp Stony (LPS) coral that are commonly referred to as either Maze Brain Coral, Brain Worm Coral, and Ridge Coral. They are a hardy, easy to maintain coral in the reef aquarium, makes an excellent choice for the beginner through advanced reef aquarist. It's an uncommon Large Polyp Stony (LPS) coral, not found all over, that are commonly referred to as either a Maze Brain Coral, a Brain Worm Coral, or a Ridge Coral. If your reef aquarium is geared toward top-end LPS, the Maze Brain Coral would be a great coral worth considering. Platygyra colonies in the ocean are usually massive and either dome-shaped or flattened, with various color shades and contrasting valleys which are fluorescent under actinic lighting. Its genus name, Platygyra, was derived from the Greek words platys (flat) and gyros (wide circle), which describes the maze-like channels in its calcareous skeleton.
Aggressiveness This coral is semi-aggressive in temperament and will expand its sweeper tentacles at night well beyond the base. It is important to leave space between it and coral neighbours in the reef aquarium.
Low-Medium water flow is best
This type of coral is very beautiful and under the right conditions it produces some amazing colors. In order to make the most of its coloration it needs to be under LED's or grown under Hybrid T5/LED combination. In order to keep this type of coral healthy you need to have a light that provides at least 3 watts per gallon of water.
Low to Mid Level. When placing them in the aquarium give them plenty of room since they have very effective long sweeper tentacles that will sting neighbouring corals that are too close.
Diet and Feeding
For continued good health, calcium, strontium, and other trace elements should be added to the water. At night their feeding tentacles extend on the inside edge of each polyp. If you feed them regularly with frozen PE Mysis, some marine snow and phytoplankton too they will reward you with fast growth.
Favia Corals are fairly quick growers and will produce a significant amount of new growth every year. Fragments can be taken, and in our experience the easiest way is with a straight-edged razor blade. With the blade perpendicular from the edge of the coral, cut inwards about an inch. Repeat about an inch away from the first cut, then snap off the section between the two incisions. Even small frags tend to be extremely hardy and easy to acclimate.
