What's the difference between dogface and narrow line puffers

[FinnCole]

Besides appearance do they need diffrent tank size ? I heard some people say narrow lines are smaller others say they get the same size

Here's info from thepufferforum.com:

They seem to be very similar

I never had a dogface but I did have a narrow lined. They are great fish. Really fast growers. Huge appetite. I say just treat them the same. The only difference from what I read is that dogface puffers are some times shy. My narrow lined was very bold. Not aggressive, but always front and center.

Yeah some puffers are more aggressive than others, some are more shy
