What do corals eat for lunch? “Every coral eats differently. Stony corals are the reef builders, and most of them are photosynthetic—they filter phytoplankton and zooplankton out of the water, but mostly they rely on their symbiotic algae for food. Hard corals, like our elegance coral, receive finely minced fish, shrimp and clams every Tuesday, Wednesday, Thursday and Friday. The tentacles work together to catch the food and have stinging cells, called nematocysts. When a fish, shrimp or plankton brushes close to them, they sting them and catch their prey. The tentacles have barbs, which hook the prey and pull them inside the mouth. The crabs that share their tank help by eating the coral’s leftovers!”—Thomas Wippenbeck, animal keeper
