What causes a puffer fish to blow up?
by
Pufferfish will “puff up” as a defense mechanism if they are threatened. A shape that is more than double its original size, round and sometimes covered in spines is much more difficult to bite and isn’t very appetizing to a predator.
When a puffer fish puffs up, it takes in water to increase its size. This violently forces the puffer’s organs to be pressed to the side, inside the body causing the organs to flatten. This creates an extreme amount of stress for the pufferfish. In some cases, the pufferfish dies from this stress.
What happens if a puffer fish inflates above water?
If the fish is inflated on the surface, it is likely to ingest air. The air can be difficult to expel and can cause the death of the fish, since the fish floats and can not leave the surface. However, if the fish is inflated under water, it only ingests water and has no problem deflating once the danger has passed.
Of course, this would harm the puffer fish, and if it were unable to heal itself or otherwise recover from the puncture, especially if it was a large wound, the fish would likely die in the wild due to screwed up buoyancy, lack of its defence mechanism (inflation), as well as blood loss and intense pain.

Can you touch an inflated puffer fish?
The pufferfish’s skin is covered in spines and spikes, which are exceedingly hazardous. Carry a toxin called tetrodotoxin (TTX), which is deadly to other fish and humans. You should avoid touching a pufferfish, especially if it is “puffed out.” Your hands could be damaged and you could die.
Can pufferfish breathe above water?
Pufferfish can balloon into a spikey sphere within moments of sensing a nearby threat, and while it may seem like these creatures hold their breath as they inflate, they can actually breathe as they puff up.
Why is my puffer swimming at the top?
Unlike you, he uses his gills to breathe the air that’s already in the water. However, in some circumstances, there’s not enough oxygen in the tank for all of the fish to breathe easily. To combat this, they swim up to the surface, where the water is oxygen-rich.
Do puffer fish like high flow?
They do well in smaller tanks, and a pair or trio can be kept in a desktop tank. A good filter helps maintain water quality, but make sure the flow isn’t too strong. Puffers in general are not strong swimmers and seem to prefer areas with lesser water flow.
Puffer fish are best known for their ability to inflate like a balloon, but if you peer inside, you typically won’t find air. You’ll find water. Puffer fish inflate by sucking water into their mouths and then pumping it into their stomach, which inflates like an accordion.
How long can a pufferfish last out of water?
They can suffocate and die quickly without water (following three to four minutes of no gill movement), so it’s important that you don’t take them out unless the new water is ready for their transfer.
How long can a puffer fish stay puffed up?
It is only a matter of a second or two. However, if they are out of the water when they inflate they fill up with air and when they decide to deflate, it takes them a bit longer. I would estimate three to ten seconds for most I have seen.
How long can pufferfish stay out of water?
On average, fish can live about 10 minutes outside of water but can die faster if they land on an absorbent surface.
Can you eat puffer fish?
Fugu, or puffer fish, are luxury fish that are used as ingredients in food eaten all year round in Japan. These fish are actually poisonous, and they can only be served at restaurants in Japan where a qualified fugu handler works.
How strong are pufferfish bites?
The average bite force of a pufferfish is around 62050 Pa and the one of the strongest species of piranhas (black rhombeus piranha) is around 12065. So looking at them individually, the puffer wins.
Almost all pufferfish contain tetrodotoxin, a substance that makes them foul tasting and often lethal to fish. To humans, tetrodotoxin is deadly, up to 1,200 times more poisonous than cyanide. There is enough toxin in one pufferfish to kill 30 adult humans, and there is no known antidote.
What eats a puffer fish?
Because they are covered in poisonous spikes, they have no real natural predators except sharks, which typically do not mind the presence of the poison.
Why do they put carrots in pufferfish?
Do puffer fish know their owners?
Pufferfish are among the most popular oddball fishes for freshwater and brackish-water aquaria. They are very entertaining fish, full of life and constantly on the move. Most also seem to be quite intelligent, quickly learning to recognize their owners and often becoming tame enough to be hand fed.
What scares a puffer fish?
Tap the puffer with the handle of the net. It will probably just swim away. Follow the puffer with the net, continuing to tap it. This will eventually either scare or anger the fish into puffing up.
