Review on Enhance Your Aquarium's Health with Boyd Enterprises ABE16708 Freshwater Vitachem - 4-Ounce by Melissa Walker

My fish are much healthier after adding this to their feed. I would highly recommend it to any fish farmer. Any dry food takes this well, especially freeze-dried foods. The previous bottle was past its expiry date so I ordered a new one. They usually keep for about 4 months without refrigeration and about 8 months in the fridge. I add 3-5 drops to her food every time I feed my 30 gallon tank and I still have plenty left over if I feed her 2 or more times a day. I've added a picture showing the old vitamins on the left versus the new bottle. to the right. You can tell it's going bad if there's a strong odor (not very smelly), while a new one is virtually odorless. The mixture also changes color from light yellow to dark brown, and the tiny round granules also change color from white to dark brown. You can tell it will go bad if your fish avoid food soaked in it, even though they are usually crazy about it.
