Recommend Me A Puffer For 180L Tank

[BecciMac1987]

I want a chunky 7" GSP, but cant be bothered with marine/high brackish. What large puffer can I keep alone in a 180l tank, in freshwater?
I want a wet pet as opposed to a fish tank iyswim.
Was thinking Nile, but do they get too big?

Here's a pinned topic from the oddball section on puffers could be a good start for you.
