Can anyone Id?

This thing looks a bit like an aptasia but it’s larger, thicker and darker. It also only seems to be out at night.

I’ve been feeding reef energy of late and my odd critter population seems to be booming.

just want to know if this is something to be worried about.

Big aptasia?

Looks like a worm. Try feeding it a chunk of fish and see what it does.

Whatever it is, it's very cool looking. Following in case there's an update.

Those are tentacles from a sea cucumber, like a sea apple but a different type. Look up Holothuria leucospilota and see if it's close.
