I had this porc puffer (his name is Buddy) for about 4 months now. Shiny finish? No.. He looks kind of rubbery
His fins are clear (with no spots). I think his latin species name is Diodon Holacanthus. It can grow to 12 to 20 inches in home aquariums.
If you see a porc puffer that has spots on its fins, that is a Diodon Hystrix... it can grow to like 20 feet or something humongous like that... it should not be kept in home aquariums...
Here're two more pics to share with you:
These ones were taken a while ago... now, Buddy has grown longer and wider... eats like a wolf/pig..
