Ok so I have an L168 pleco who I absolutely love and I noticed he hasn't come out at feeding time for the last 2 days (which is very unusual) I decided just now to have a quick look for him to check he's ok but he's totally disappeared. This pleco is about 6 inches and he was absolutely fine and eating 2 days ago... the largest fish I have apart from him are angels which never go to the bottom and a bolivian ram so it seems unlikely that he's died and been eaten.. I have dug up all the sand and nothing.. there is no holes or anything he could have gone up... Any ideas?!?
