My local Petco has a pretty cool looking puffer fish that likes to bury himself in the sand when scared. He's labeled as a checkered Puffer and is about 3 or 4 inches long. They've had him for a few months now and he is pretty healthy looking. Thinking about maybe getting him but couldn't find much info on them out there? Practically nothing. Anybody familiar with this fish? Wondering if Petco has mislabeled him, as I know that sometimes happens.
