I popped the top to one of my powerhead and it was full of life. Is this some type of brittle starfish?

It's a typical mini-brittle star. It has probably reproduced recently. The smaller arms will grow quickly.

Yup. It is Ophiactis. It divides in half and each side regenerates the other. Pretty common hitch hikers, especially in various refugium settings. Good to have. Eats detritus and stuff. :)
