What is on my elegance coral?

DeanoL · Oct 28, 2023

Hi,

Had a peek at the tank early morning before the lights were on and saw this on my elegance. Easy to see as it was all sucked in !

Do I need to worry about it?

Thanks for any info.

Could be a flatworm, if so I'd do a dip. @ISpeakForTheSeas any help?

A sponge?

ISpeakForTheSeas · Oct 29, 2023

Can you describe the specimen a bit:

-Is it hard or soft?

-Does it move around?

-Does it open and close/expand and contract/extend and retract?

-Does it have any noticeable openings/holes in it?

My current guess would be either a sponge or tunicate (both of which should be totally harmless).
