You know baby puffer fish look like out of the water

People are asking about taking a puffer-fish out of water.

In a past life, I used to import tropical fish, and one of the most popular is the Porcupine Puffer (Diodon holocanthus). We have all seen them in fish tanks or in Finding Nemo, and they are actually pretty good aquarium fish, with a big enough tank and the correct tank mates.

We would transport a huge number of these, and while we really tried not to stress them out some would puff up sometimes. If they puff up underwater it is not a big deal, but the issue was if they puff up near the surface or out of the water they swallow air. They have a hard time getting an air bubble out and it will actually end up killing them.

So, when we got the puffers in we would see if any of them had swallowed air, and if they had I would have to “burp” the puffer, which entailed grabbing it and holding it face up at the bottom of a tank, shaking it which would get it to puff and then relax a little until it burped out the air bubble.
