Fish is running 70/14, AF = 1.5 and this seems a good spot to get his stack. Two questions here really.

1. Is my flop raise enough? Is there a reason I would want to blow him out or am I so ahead of his range I need to keep him in?
2. Any reason to ever flat turn?

you think you are really ahead, but with his line, what are you putting his range at? I think you are ahead, but I hesitate to say you have him crushed.

Raise more flop, shove turn.

Considering you there will be less than a 1/2 pot sized bet left on the river and you are in position, I don't mind flatting the turn bet. There aren't really any scare cards. But the pot is getting big, and it is a fish, so you can get it in on the turn and feel comfortable.

Sign me up to this line!

I love this. I think you're in great shape.

How many hands are his stats based on? Did you look at his bet % on the flop?

Is he a fish because he calls 70% PF or because he overplays his hands post flop? Him just calling here is pretty weak.

I like the $5.25, although, I would have bet $6 just because I typically just triple the bet and try to get more in.

As played, on the turn this is an insta-shove. Him flatting the raise on the flop screams top pair because i think he would have 3bet with a set or 2pair. Though, you are running that risk that his TP came with an A kicker.

Still, if he's been playing donktastic, I shove the turn and take the hit or the win.
