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.

The Ultimate Diaper for Babies on the Go!
Size: Size 7, Unit Count: 88
As a parent, I'm always on the lookout for products that make life easier, especially when it comes to diapers. And let me tell you, these diapers have been a total game-changer! Not only are they the best for my active baby, who's always on the move, but the convenience factor is off the charts. These diapers are designed with active babies in mind. They stay put, prevent leaks, and allow my little one to explore and play without any discomfort. The fit is snug but flexible, providing maximum comfort and protection, whether we're crawling, walking, or just having a playful day at home. But what truly sets these diapers apart is the incredible convenience. There have been times when I was in a real pinch, running low on diapers, and the thought of having to drag my baby to the store was daunting. Thankfully, with these diapers, I didn't have to! The fact that I could order them online and have them delivered straight to my door was a lifesaver. No more lugging around those massive boxes from the store; all I had to do was bring the package inside and put it away. It's a simple thing, but it makes a world of difference in a busy parent's life.

They're not all cracked up to be!!
Size: Size 4, Unit Count: 144
Bought these diapers because I heard such great things about them. But quality of the diaper was very poor. When my son had a wet diaper, the diaper really didn't absorb the wetness, so I would have to be careful when I changed because it would leak out once I tore the sides. I'm on a very tight income and regret chosing these because I don't have any extra funds to replace them and also chose to try these out because my son is a wiggle worm when changing him! Also, consider going down a size because these were huge size difference between size 4 little snugglers and these.

Comfortable, reliable, and super convenient for everyday use
Size: Size 3, Unit Count: 136, Size: Size 3, Unit Count: 136
I’ve been using these diapers for a while now and they’ve honestly made things much easier for us. One of my favorite features is the pull-up (pant-style) design. It’s especially helpful when the baby is active and doesn’t want to stay still during changes. Compared to traditional diapers, these feel much more convenient and quicker to put on. In terms of comfort, they are very soft and lightweight, and my baby seems comfortable wearing them for long periods. I also really appreciate that they are unscented — there’s no strong or artificial smell, which is something I’ve noticed with other brands. Absorbency has been great so far. They don’t feel overly wet even after extended use and have held up through the entire night without leaks, which is a huge plus. The inside material stays evenly distributed and doesn’t become lumpy, even after several hours. Pros: Easy pull-up design (great for active babies) Soft, lightweight, and comfortable No strong scent or odor Good absorbency without feeling too wet Reliable overnight protection Holds shape well (no clumping) Cons: Slightly different from traditional diapers, may take a bit of getting used to Overall, these have been a very reliable choice for us. I’ve already reordered them multiple times, and they’ve consistently performed well. I would definitely recommend them to other parents looking for something comfortable, convenient, and dependable.

Leak Proof!
Size: Size 5, Unit Count: 56
These are great for overnights! They do not like and you don’t have to worry about not putting it in correctly as you struggle with a rolling alligator. I’m a fan because they do not leak like others while the kids sleep.

Great for Sensitive Skin
Size: Size 5, Unit Count: 128
I've tried other diapers and I keep coming back to Huggies as they are the only ones that don't cause irritation for my little one. Little one is 12kg and we use size 5. They are very roomy but still snug enough around the waist. I'm amazed at how absorbent and soft they are. Although there are "cheaper" diapers out there, they don't hold as much and aren't as comfortable.
