I got a bubble coral that was damaged. I remember someone that damaged theirs and it came back. That's why I got it because I've always wanted one. Right now it has some small bubbles on it plus the top part is all green could be algae. Do I need to remove it or will it be alright? I know they are fragile so I don't want to damage any of the bubbles. Also it's at the bottom of the tank with very low flow if any.
