What can i house with a GSP?

[Keiko3]

I know puffers are very aggresive but ive seen them housed with many different catfish and schooling fish?

What you have to realize is that GSP's eventually will need to be transitioned to saltwater, and a lot of the fish you see with them, like catfish, are freshwater only species. They're also different from specimen to specimen - one GSP might not mind a tankmate or two, while another might attack anything you put in the tank with it. Also, that nice GSP you had for years might one day wake up cranky and kill one or more fish in the tank with him.

Ok thank you.

Depends on how big your aquarium is.
