Spewy Turn call?

CO in this hand is a standard TAG, the BB is your 40/20 fish.

Pre flop is standard to me based on the price I'm getting laid as well as my position. Flop call is standard I think also. Its a bit interesting though, that the CO has called the flop in front of me. I can basically narrow his range down to middling pairs like 77,99,TT and some draws like QTs T9 combos and some broadway flush draws. The fish can still have a wide range, including some strong made hands and some random no pair hands.

On the turn I'm not too sure what to do. BB's range is now more narrow and skews toward stronger made hands and the fact that CO calls again on this turn strengthens his range in my mind. I'm getting almost 5:1 here but I feel like calling is a bit spewy based on their ranges and folding is a bit nitty based on the price I'm getting. What do you guys think?
