I found this weird fuzzy thing on my coral last night. I thought it was just a piece of coral tissue. Then today I found the samething somewhere else. And notice one of my corals branch’s was not open. I placed every picture I took below so that way you guys have multiple pictures to choose which is best to view. Thank you guys.

Hard to say for sure from the pics, but possibly a pineapple sponge.

My look says pineapple sponge.
