I bought this little guy at Petco (I know, I usually don't buy fish there but they just remodeled the fish area so i had to check it out and I saw him and he stole my heart) he was labeled as a "green and yellow spotted puffer". He is about an inch long with tail extended. When I first got him he was about half an inch. That was about 3 weeks ago. Do you think he is a GSP or dwarf?
