Did I miss a protection raise on the turn?

MP1 is a full on fish. CO is a TAG who had a late post. Button is weak/tight post-flop 25/9/1.4. BB is a TAG.

Flop and turn were great for my hand, but I screwed this up on the turn I think. I should have 3-bet, yes? I was thrown off by the raise from the button...

When _would_ it have been correct just to call down? Never in a multiway large pot right (he says after the fact)...
