As many of you may have noticed on your own Ocean-Zoo tanks, there is a hole directly in the centre of the tank floor next to the crater. I'm guessing that this is for that glow-in-the-dark haunted ship add-on thingy, but all it's being to me and my smonkeys is a total pain in the bum. My smonks often swim into it and then get stuck because they can't swim backwards.
Does anyone else have this problem and what do you guys do about it?
