The Live Acanthastrea Echinata "Starry Cup" Coral is one of our favorite corals. Some of the colors found in these corals is amazing. They can be aggressive to other corals so care must be taken with placement. Echinata corals do well under medium light and low water flow. Regular feedings are a must for this coral for long term health. For other colorful coral, check out our selection of mushroom coral for sale.
