Can anyone ID this puffer?

I was scrolling Facebook marketplace when I came across this guy- I don’t know much about puffer fish but I do know that pea puffers in there entire 1 inch of length need 20+ for their shoal to be happy so I just can’t imagine this 3 gal set up is good for this guy. I mean I wouldn’t even put a group of guppies in a 3 gal. Not even mentioning the decor.

I wasn’t planning on getting a puffer fish but I feel morally not good about leaving this as is after seeing the listing. He looks so sad :(

Anyone in the Orlando area looking for a puffer? Anyone know what kind of puffer he is?
