What's even cooler than two underwater waterfalls?
Last year, we published an article of a gorgeous two-waterfall aquarium; FYI: the article also explains what underwater waterfalls really are (sandfalls) and has a tutorial video for creating sandfalls in case this is something you want to try yourself (and it is something you want to try). The aquarium spotlighted in the article featured two impressive, towering sandfalls on opposing sides of the tank.
This newly published video below is of an Indonesian aquascape, which adds one more sandfall into the composition All three sandfalls are relatively low-profile, giving the rocky hardscape its unique aesthetics. We only wish there was a higher resolution video of this aquarium.
With an aquarist's ingenuity, there is a lot of potential to create even more beautiful and imaginative sandfalls.
