Hello little friends !
All I know about puffers is , first of all , they are cool.
Not sure but they might be a bit difficult to feed but once you find something they like you’re all set. I’ve heard crushed snails. They like snail meat so you might want to have plenty available.
They are , supposedly , touchy about water conditions but I don’t know in what way.
One other thing I heard is that they are very social and prefer plenty of their own company. If that is all puffers or just one species I don’t know.
Just my own particular opinion here is that I would have them in a species only tank. They might nip other fish. Supposedly they like to bite and tear out chunks. Also, slow swimming as they are other fish will out compete them for food.
