I'm guessing the tower is made by sucking all the air out of the tower, then the water gets sucked into the void.
For some reason, don't think this is a good idea for a betta, at least. If he was at the top and suddenly needed air it'd be quite a way to get down and back up to get to the air, since I doubt they plan ahead. but it looks awesome for other fish :D
taking a break from fish-keeping.
3 lovely male betta still keep me company.
