Caulastrea SuperSale Pack 2x 2 heads The Caulastrea SuperSale Pack is an incredibly affordable package featuring two colors of Caulastrea,  with 2 heads of each. Caulastrea Echinulata Frag (Green Heart) 2 heads + Caulastrea Ultra Green Frag 2 heads. These corals are a beautiful addition to your aquarium, available in various types, sizes, and colors. A Caulastrea is generally easy to care for, even for beginners. The coral grows best when water parameters are in good condition, meaning that a small amount of phosphate and nitrate should be present, and of course, the rest of the water parameters should also be in balance. These corals feed primarily on light (preferably T5), but they can also be supplemented with various types of powdered food, and of course, with artemia and mysis.
