I noticed my pleco doing a little wiggling inside of its favorite little hide in the driftwood. Curious if this is normal behavior of maybe it's chewing on the wood or something else

I'm pretty sure this is a clown pleco. That's how it was sold to me and as best I can tell from its markings, I believe it's too young still to identify sex yet. Sorry for somewhat low quality pictures, my tank has 3/8 in thick glass and it messes with the camera trying to focus.
