@why-animals-do-the-thing an example of trainability in fish! Harder in long-tailed male bettas because they can’t really clear the water, but bettas can be taught to swim through a hoop, and this is the next step up. They’re smart fish who are easily motivated by food. 

And that thing in the background is a betta hammock. Bettas like to lounge near the surface of the water so they can easily wiggle up to the surface for a breath, and some will even lounge in areas so shallow they’re barely covered by water. Their favorites are places where they only have to lean their head up for a breath.
