Hay I'm fairly new to reef2reef this is my first post but anyway I was looking in some of my rocks today and saw a glowing blue dot I took a couple pictures and was wondering if anyone could identify it

Based on the first picture I would say it’s some type of sponge but that second picture has me scratching my head.
