Could be a chiton or a Sand Skater. Hard to tell with the picture.

I hate to say it, but you may have what looks like an oval fuzzy white thing in your tank!

Peel it off the glass, put it in a bowl that is a contrasting color and take a couple of good close up photos... then post them.

Seriously, get the better photos and you'll get more and better quality replies.

More than likely a chiton.
