It does look like some sort of spong but to be directly in the light idk and also I have white sponges growing in ym tank but they fade when exposed to light over days they only grow in the shadows.

Some sponges can grow just fine in light.

I thank you guys for the input, please keep it coming ... I should tell you guys that the growth seems to be on the bottom side of the zoa's where it might be a lil shady... Could that be it???
