Do betta fish float when they die?

Not all betta fish float after death. In some exceptional cases, when a betta fish dies, this means the blood circulation and heartbeats are stopped. But there remains Oxygen in the float among the betta fish body. After the death of betta, fish tissue gradually breaks down. It also adds more gas, especially in the gastrointestinal tract.

As a result, there is no way to let the gas escape, but the gas pushes the betta fish’s belly to inflate it. It turns the dead fish into a kind of fish balloon and rises towards the water’s surface.

However, depending on the depth at which the betta fish died, it may not rise from the surface, at least until the decomposition actually begins. Generally, most fish do not have enough ability to float in the water.

In addition, betta fish have an organ called a swim bladder. When alive, the specific gravity is adjusted so that they can stay at the desired depth in the water by putting gas such as air in and out of this bag. But when you die, the same is true for pre-death and weakened fish. Since the adjustment cannot be made well, the stomach with gas will come up.

Betta Fish Swim Bladder Disorder:

Every fish has an organ called a swim bladder, which helps control fish position in the water. Betta fish are not exceptional. When betta fish rise in the water, they take air into the swim bladder organ. And if betta fish want to sink in the water, they expel air.

Actually, when the swim bladder organ is damaged, it is called swim bladder disorder. Therefore betta fish cannot adjust swim bladder functions, and standard body functionality is stopped.

As a result, the gas generated by rotting internal organs becomes superior to the swim bladder and floats on the water’s surface.

In fact, even if you are alive, gas may accumulate in your body due to indigestion, etc., and it may float if you cannot discharge it to the outside of your body. This is caused by the inability to adjust the swim bladder or damage to the swim bladder due to the gas accumulated in the body.
