So in planning out the layout of my tank i saw an opportunity for a hollowed out hill against the side of the tank. In other words it would be a cave but two sides of the cave would be glass. Just wondering what the octopus' reaction to this would be, would the cave get used and if not could this be fixed by a piece of black cardboard against outside of glass? Also saw this as an opportunity for at night using a red light to look in on the octo while it was in cave.
