Most quality fish foods will have a strong odor due to a large portion of the raw ingredients being comprised of fish, krill, shrimp, etc. That's a good thing!
If it doesn't stink, you're probably feeding a fish food that has a large inclusion rate of terrestrial based plant matter, such as wheat, corn, soybean, peas, rice, etc. That's not a good thing.
If odor is an issue in the bedroom, my suggestion would be to run carbon in those tanks, not to feed lower quality starch laden food.
