How long is refrigerated fish safe to eat?

In my experience, COOKED FISH IN THE FRIDGE would be good until the next day only (14hrs. tops), unless it is packaged: tuna, shrimp, clam sauce, etc. any seafood pre-packaged usually has preservatives (1-2 days). I follow this rule as most fish does smell fishy, if it is too harsh for the nose and slimy, NO GOOD!!! TIP: If you have to save fish for the next day, try not to cook, put on ice tray in fridge and cook ASAP!!! If cooked eat ASAP within 10-14 hrs.
