lol no
worrying about balance against fish is just leaving money on the table for no reason at all
and fish can be extremely sensitive to bet sizes, far moreso than regs
his line and sizing up to the river have shown a lot of weakness and there's no reason to believe he'll call a large bet (the pot is 39bb so any large bet is going to be reasonably significant in relation to the stakes)
I don't want to make a definitive statement about what the exact optimal bet size is in this spot because I don't play those stakes, but based on my history with fish across a variety of stakes and game types, I'd expect the 1/4 pot bet to get called far more than a large bet. The weak bet is exactly how fish bluff and so they will call that bet with anything when they see it from someone else. The strong bet looks strong so they fold. And counterintuitively, I've found that players actually get nittier as you go down in stakes, so the fact that it only costs one cheeseburger to call the river doesn't make people any likelier to actually call with a bluffcatcher.
And returning to the subject of balance, I always size my bets based on the strength of my opponent's range. From a theoretical standpoint, no one should ever be calling you if you're betting huge in a spot where your range just absolutely crushes your opponent's range. Optimal play would be to make a small bet with 100% of your range (example: you threebet preflop and an ace or king flops: you should never bet big here because it's a very polarized situation, with your own range being ahead by a decent amount depending on the specifics of the situation). And against fish, you need to valuebet smaller to entice them to call with weak hands. You need to size it so that it looks to them like just a weak stab to pick up the pot. And of course with a bluff against the fish then you size it big enough that it reads like a value bet from a strong hand.
