I know minnows, shrimp, clams, mussels, carps, and prawns contain thiaminase, what would be some good foods without thiaminase? I feed tilapia mostly, though I do feed river shrimp (frozen), pellets, insects, and worms.
Foods with and without thiaminase

Ok thanks, I mostly feed slithers of tilapia with pellets jammed in it, for vitamin b1/b2, what's a good way to get the vitamins in? Would I be able to get vitamin pills from the pharmacy?
No, human vitamins don't provide exactly the level/mix of vitamins that fish require, better off getting a fish specific liquid vitamin solution (like Boyd's Vitachem or similar) and then sprinkling that on your frozen/fresh fish, shrimp, etc.

Not sure but prawn and tiger shrimp contain it. Forget if these are freshwater.
IMHO - when in doubt supplement with B1 3-4 times a week. If feeding fresh/frozen, pre-soak in an aquatic based vitamin/mineral supplement that is known to contain B1. If feeding live, gut load the live feed immediately prior to feeding your fish. Or feed pellets a few times a week.
