What is this?

Wondering if anyone has any idea what this white blob looking thing is. It has slowly moved around the tank on it’s own. I’ve attached two pics from two different days. The shape changes as well from time to time.

Thanks!

Thank you for responding! Can sponges move on their own throughout the tank? Employees at our local aquatic stores are telling me no. Your response is very appreciated. We are new to reef/saltwater and appreciate all the helpful info this site has to offer!

Looks like a sponge to me. If it's not attached to anything, it could be moving with the flow.
