Fish thrive

My tanks have always thrived with healthy fish. When I started using this I was amazed how my fish seemed to improve in vitality. The extra boost of vitamins really took their health to a new level. Easy to use. I add it to the water once a week or when adding new fish to boost the immune system.

Wow! Just within a couple of days...

Got this product 2 days ago and let me tell ya, it works. So, I have a 5 gallon guppy tank, a 20 gallon mixed glofish/freshwater tropical tank, and a 45 gallon fancy goldfish tank. Their colors pop and all my fin babies have loads of energy. Beautiful! Thanks Chewy. Yes, I recommend this product and I recommend Chewy.

Really Works!

Honestly you need to see the results to believe it! My fish love the taste--the vitamins have gotten them through extreme health issues and now I continue to feed them Vita chem daily. Keep it refrigerated--soak food pellets in the vitamins until saturated and feed to them!

Highly recommended

After almost 30 yrs in the hobby I finally discovered this through a bona fide fish professional. He shares an abundance of useful knowledge making YT vids(adding this to their food by soaking, and if a fish is really ill he also adds it directly to the water. See directions on bottle for both)... His fish don't just live for years, they absolutely thrive. I'm thrilled Chewy is carrying it now!

Wish I had known about this sooner!

I only started using this product a few weeks ago as my betta contracted fin rot (water parameters fine, large tank, planted, no idea why betta is sick) and this was recommended by someone. While this product wont cure fin rot, I can already see a difference as my fish's color is brighter/deeper. I wish I had used this from the beginning to help ensure my fish has optimal food. I soak pellets, bloodworms, brine shrimp in this and then give it to the fish.

Give them the best

I’ve been using VitaChem for a couple of years now, and the fish seem to love the stuff and are thriving. I just discovered it on Chewy, so now I have a quick, well-priced option. Thanks, Chewy!
