What do you know about coral

Yes, what do I know about coral. really not that much.
Is Coral naturally white? I googled it and here's what I found out.:

Coral bleaching happens when corals lose their vibrant colors and turn white. But there's a lot more to it than that. Coral are bright and colorful because of microscopic algae called zooxanthellae. ... As the algae leaves, the coral fades until it looks like it's been bleached.

I did have a sea aquarium for many years. Stop with it because the glass was broken on our holliday and all the water get on the floor and everything living in it was died. To keep it in good condition need a lot of knowledge .
