Anything with a mouth eats its common sense and backed by science that corals eat and eat a lot. Some corals can get the majority of the energy from photosynthesis but none can get their amino acids needed for growth without ingesting them. I don't know why this debate keeps going on, it's been proven 100 times over the corals eat, including sps corals they have developed hundreds of mouths for a reason. In saying that, it doesn't necessarily mean you have to feed them directly but it does increase growth and sometimes improves colors.
I didn't say they didn't eat. I just said it wasn't necessary to feed them
