Puffer Fish Identification / Help

[jaxco]

Hi! my girlfriend bought me a fresh water pufferfish yesterday but we don't know exactly what kind it is or how to care for it. Here are some pictures of it, if anyone could let me know how to care for it that would be great! It is yellowish green with brown spots and about 1.5" long. thanks!!

looks like a green spotted puffer, they are brackish fish so they will need salt, they are also AGRESSIVE they will eat goldfish.

1.008 i believe is what they should be kept at specific gravity wise. but yet looks like a green spotted puffer. brackish water, mix between saltwater and freshwater.
