I’ve just recently done a water change on my fishtank, I took out all the ornaments as well as the bogwood for my clown pleco, I popped it on or near the side of the tank. I went to fetch some water to put back into the tank to find the small piece of wood had fallen back in. I lifted it up to find my pleco was underneath, but not crushed etc so I don’t believe he was directly hit ? But I don’t know whether it stunned him? The pleco seemed to be moving but kept freezing and refusing to move. I took him out the tank and put him in a separate jug with aquarium water in it, and he swam fine, but suddenly went on his back? I left him for 10 minutes and he seemed fine so I popped him back in the tank, then it started to twitch and froze again, it hasn’t moved now for 1 hour and I don’t know whether or not it’s dead or he’s just stressed/stunned by the wood falling ? Please could someone help, I’ve linked a photo of what he looks like
