Weird grey/clear dead dianthus growth

Does anyone know what’s up with this small zoa colony? It seems to be growing but what’s growing doesn’t grow heads.

Looks like there is a translucent sponge encroaching on the frag plug. Usually these are harmless filter feeders, but they can be killed by injecting them with air, boiling water, or hydrogen peroxide.

Thank you I’ll look into it!
