Blue hypnea?

Could this be blue hypnea? It’s blue under white lights also.

Tough to tell the shape from the angle, definitely has the color.

Not even close. My bet is a sponge.

It's a macro forgot its name it can spread fast so most dont like it. I gotta look for the name

It's a brown macros cause I have something like that in my tank. It's spread like wildlife and is quite difficult to get rid of.
