I take it that you did NOT qt him? I am sorry, but you knew he was ill and added him right in? It could be anything comming from the dealers tank, you don't know what stresses and terrible conditions he may have come from. Do you have a qt set up? If you do, pull him out and observe him for awhile!
Jeeze, I was just looking at the pics again, that could be anything from an infected bite from another puffer to a bacterial infection, It is never a good idea to buy a fish you already know may not be well.
Could you list your EXACT water parameters and how long this tank has been set up, also how big is your tank?
