Get it right, the coral is keeping you ;)

Actually not true. Corals photosynthesize. Almost all corals except for select deep water species that are non photosynthetic. I’ve been keeping saltwater reef tanks for years, and I assure you, coral is an animal, and coral can photosynthesize

Isn't that more like a symbiotic relationship?
The animal in the pic is a nudibranch (naked gills).
"Some nudibranchs, like the Blue Dragon, create their own food by eating coral with algae. The nudibranch absorbs the algae's chloroplasts (zooxanthellae) into the cerata, which acquire nutrients by photosynthesis using the sun to sustain the nudibranch for months. Others have evolved other ways of farming zooxanthellae, housing them in their digestive gland."
