For those that aren't familiar with the Thera A product, the following is from the creator himself; Thera A is a non-medicated food that contains a mega dose of allicin compound which is found in garlic.
So yeah, no kidding it smells like garlic. Then add krill to the mix, and you have the potential for a stink bomb with the TheraA. Personally I would be more worried about feeding my fish food that didn't stink. Krill based food should stink like krill, shrimp based food should stink like shrimp, food with garlic should have an odor of garlic, etc-etc. If they don't you are paying for fluff, not what's shown on the label.
