StressGuard 500 mL / 17 fl. oz.

This remedy works great. I have mostly swordtail fish and they were sick. After their treatment, I gave them Stress Guard and they all calmed down dramatically. I am so grateful and happy with this product.

I use this whenever I see that my large fancy goldfish have any signs of injury like torn fins. It really works!

This is a legit brand in general. I will always purchase it over any other brand for its ease of use, efficiency and saves you from needing anything else. I like that the stress guard does what takes 2-3 other types of additives would do. Lowers ammonia just as the prime ammonia does. Will not harm your water current beneficial bacteria while boosting helpful ones that also coat the fish. A small size works great for 10gallons but larger bottles last me a year or more with a couple 10 gallons so it's worth it. All I use is this and basic de chlorinating solution. Maybe once a month with a tank change and it keeps my aquatic friends happy.

One of the few medications available for freshwater aquariums that's safe with live plants, scaleless fish, and invertebrates. Invaluable. Contains a safe form of copper.

Big bottle for a great price. Nobody sells this product around me
