Found this in my zoa colony while examining everything any ideas??bad good? If bad dip? Is those bluey coloured things?or is it just a sponge?

Ok thanks, so nothing to worry about then.

Sponge can spread and overcome corals... Although not really invasive in any manner I've seen it can eventually overcome another coral.....if it is in fact a sponge then you can try the exposing to air method.... However, I will testify that even when exposing sponge to air it will jot always kill it and may require manual removal by scraping or such.

Those black sponges don't grow fast at all..  The zoa overtaking ones are kinda white and fluffy and fast growing
