Pleco Problem, What should I do to comfort it?
I bought my pleco a month ago. It seems to be healthy lately and it eats the sinking pellet that I feed him at night. But just at the moment my, pleco seems to be keep on going up the tank, resembling floating upward. It is not spending its time on the aquarium floor as before. When It is sticking to the glass, it's tail tends to turn up so he's upside down when sticking to the glass. What should I do then? I'm concerned of the fact that he is sticking to the chalice all of the time, as before, he usually spends his time between my big shell ornaments.
