Yes and they float
Well ehen they float in the water that means there dead.you dumney
no, silly, or puffer fishes wouldn't exist!!
Fishes do not exactly float, except when they die. Although fishes can move upwards and downwards by rising and sinking, sort of like a helium filled balloon. To do this, fishes need to reduce its overall density by reducing its volume without increasing its mass. For this, fishes have what we call a 'swim bladder'. This an organ that expands and contracts, just like a human lung. When the bladder is inflated, the fish has a maximum volume and is pushed to the surface. When its deflated, it has a minimum volume and sinks. In this way, fishes are capable of rising and sinking and also staying at a particular level. Hope this helped :)
They would die.
i dont now try it!
The swim bladder helps the fish float right and balance. If a fish has something wrong with its swim bladder, it will have trouble swimming down and will soon get stuck upside-down and die.

Because they will die.
