Help to identify black creature living inside favia

[ewanho]

Please help to identify this black soft organism that is living in my favia;

about 1cm, retreats inside if you try to touch it with tongs or move the favia, like a bag; but doesnt protrude out the other side of the favia

Going to say black tunicate. Like to hide in small gaps and crevices.

It says their skin is toxic, but it seems to just be a filter feeder. Pretty neat!
