Why is my fish upright?
A: Many bony fish, like the fancy goldfish found in ornamental ponds, have an organ called a swim bladder. This gas-filled sack has two main purposes: It helps the fish control its buoyancy and remain at a particular depth without having to waste energy on swimming, and it keeps the fish in an upright position.
Why do bettas float to the top?

Myth #1: Sharks Must Swim Constantly, or They Die Some sharks must swim constantly in order to keep oxygen-rich water flowing over their gills, but others are able to pass water through their respiratory system by a pumping motion of their pharynx. This allows them to rest on the sea floor and still breathe.
