my gf orderd me a porcupine puffer for my bday, i currently have a green spotted puffer 4.5", a 2" sharpnose white spotted puffer. Would the porcupine pose a problem? my GSP is super nice and wouldnt harm a fly...well maybe a fly but hes never gone after another fish, and my little white spotted guy is timid and always zipping under rocks, but he will come up to the glass as stare right at you too...both will hand feed and my GSP will even let me pet his back...he seems to enjoy it haha...and those two get along just fine...just curious if they would pose a problem. Yes i am aware at how large the PP gets i have a 220 gallon lined up in 6 months which should be plenty of room. what do you think?
