Nourishing and immune-boosting food for Koi, designed for feeding throughout the year


  • floating pellets featuring a unique ring and core structure
  • enriched with probiotic active bacteria to enhance and stabilize intestinal flora
  • promotes health and optimizes feed utilization
  • Koi develop robust health, build a strong immune system, and contribute to cleaner water
  • high in protein for optimal growth

Probiotics are now recognized beyond yogurts or dietary supplements for humans—they have become an essential part of ornamental fish nutrition. Since 2016, the intestinal flora stabilizer Bacillus velezensis (previously known as B. subtilis) has been approved for inclusion in ornamental fish feed, receiving explicit endorsement from the EFSA (European Food Safety Authority) to enhance growth and feed efficiency.

sera was the pioneer to respond swiftly in 2016 by introducing an innovative probiotic koi food: “Koi All Seasons Probiotic.” As part of the brand's rebranding initiative, the name was updated to “Koi Professional Probiotic.”

Koi Professional Probiotic is ideal for year-round feeding of koi when water temperatures exceed 8 °C. The specially co-extruded granules include not only the natural, functional components that are typical of sera, such as MOS, beta-glucans, Haematococcus algae, spirulina, and more, but also the probiotic Bacillus velezensis, which supports the fish's intestinal flora. This enhances their overall health and boosts feed efficiency. As a result, koi grow rapidly and uniformly, while the water remains less polluted by harmful waste and algae-promoting substances. To reap these benefits throughout the year, this specialized food should replace seasonal diets several times a week, as long as water temperatures are above 8 °C. It also serves excellently as a primary food source.

Koi Professional line

Within the Koi Professional line, sera provides high-quality food options tailored to the unique needs of cold-blooded fish during various seasons (spring & fall, summer, winter). Additionally, there are two functional food options, Koi Professional Color and Probiotic, which are suitable for year-round feeding. Koi Professional Junior has been specifically formulated to cater to the dietary requirements of young Koi.

Excellent product for dry mouth
Scent Name: Berry, Size: 100 Count
If you are having trouble with dry mouth, especially while sleeping, this is definitely the product for you. I have severe dry mouth and have tried multiple things including hard candy (yes, I know not very smart) as well as different biotin products, the mouthwash, the spray and the gel, which all do work, but do not last for very long. These stay in place open the corner of your mouth, last for hours and truly work. I highly recommend it if you are having a dry mouth issue

Works great
Scent Name: Berry, Size: 100 Count
I have to use these for about 1/2 a year. I keep bronchitis and sinusitis from about Oct. to April every since I was a child. When I am suffering with these I can't breath through my nose, epically at night while sleeping and would wake up several times a night with dry mouth so bad ir was literally painful. My mom turned me on to these because she was using the with her CPAP. I sometimes have a bit of difficulty getting them to stay put but overall they are great. I have tried the OG, cinnamon, and berry. The OG have no real taste, but you wake up with a sweet taste in your mouth. I tried the cinnamon because I love cinnamon and didn't listen to the reviews stating how strong the flavor is, big regret, it's like putting two or three fireballs in your mouth, won't be making that mistake again. The berry ones are actually best in my opinion. They have a light berry flavor that isn't overpowering, isn't quite as sweet as the OG. Whichever one you choose you won't wake up in pain. I do suggest using only one at first as opposed to the two they recommend, unless you like waking up with your head on a water logged pillow. One generally gets me through the night unless my congestion is super bad, then I will sometimes have to use a 2nd one about 1/2 way through my night when I wake up for the bathroom and realize it's already completely dissolved.

Happy to have a stainless steel one
I'm a female and I tried a few others, but this one seems to be more comfortable in my mouth. I would've given it five stars, but I wish it had one side, a little bit rougher than the other side. I'm spoiled with the one I had which was plastic, but it was perfect. Otherwise one was a milder scraping than the other side, and I seem to like the more aggressive scraping. People who have never used a tongue scraper will be just fine with this and I'm going to stay with this one. Just have to do it more times.

Solid and dependable product
This product has had a positive impact on my oral health. It is well made of solid stainless steel, and is comfortable to hold and use. I have no doubt this product will continue to work for me for years to come.
