My 1.5 inch yellow lab, Gregory, keeps going behind my 3d background and he won't come out! He did this yesterday and he came out but now he wont. The background isnt siliconed. It stays back against the tank and the sand keeps it in place. There are barely any ways for him to get in, but these are tiny fish, so this is a problem. I think hell come out if I feed them, but how do i keep him from going back again?????
