Eh, go with the New Guinea! They are such a cooling looking puffer. Seriously though, you could not go wrong with either of them.
As far as my puffer, I feed him frozen krill and squid, with a little clam and nori mixed into his diet. Lately though, I have been feeding him red crabs to try and file his ever-growing teeth down. This seems to be working fairly well so far, but it is going to take a lot of time.
Oh, and if anyone would like to try and identify what kind of puffer I have, please, feel free. I purchased it as a stars and stripes, but it is not a stars and stripes due to it having no spots anymore. A true stars and stripes puffer retains the spots on his face and on his back. This guy does not have those spots. So please, if you know what kind of puffer this is, post it! Fenner's website was not able to ID it, and I have posted it on here when I got it and I got no ID for it. This guy is about 2 years old now and still no correct name lol.
