What is this

I’m new to this community and also very new to the hobby. I recently got a new display tank about two months ago and have since placed a few fish. Today, I saw this floating around in the tank and I’m not sure what it could be.

Can you get a better picture? It's hard to even get an idea of what I'm looking at here lol
