I dont even know the average size of a puffer fish is. for a start
A puffer fish usually puffs up and looks like a ball with spikes that was when its pray tries to eat it it will poke them and eventually leave them alone.
Nunners here, I was wondering which puffer fish you meant because some puffer fish release poison when they inflate, thus killing themselves and other fish in the tank. Or if you get the one that has shark spikes it could wound your goldfish causing it a cut, he could die because of an infection. Also i think puffer fish are tropical fish?
Puffer fish look like a circle with small spikes around it.
so its spikes come out to protect it from anything that tries to eat it
it has adapted by growing spikes to help not get eaten from its prey

they puff up like a ball with spikes. It looks something like sea urchin when it puffs up.
