Indo-Pacific - Islands of the Indopacific including Fiji, Tonga, Solomon Islands, and the Great Barrier Reef.

Medium to high lighting would serve this species well. Leptastrea can be kept under high output fluorescent bulbs, but may benefit from more intense lighting. It will likely change its coloration depending on the lighting provided. Leptastrea may require a longer acclimation period to intense lighting such as metal halides.

Moderate water movement is recommended.

Leptastrea relies heavily on the products of their zooxanthellae. This coral may benefit from the addition of phytoplankton as a food source. While the coral itself may consume some phytoplankton, the real benefit is the increased population of rotifers that feed on the phytoplankton. Rotifers make a good meal to a vast array of corals. If phytoplankton is not readily available, you may attempt to feed the coral finely ground meaty foods. The food should almost have a paste-like consistency before being administered.
