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.

Great product and great value
Color: Beige
Was not sure I would be happy but took a chance and bought this Neretva machine. Love the small footprint and it looks so high end on the coffee bar. So I read the instructions as well as a bunch of reviews and then gave it a go for a cappuccino. Success on the very first try and it was restaurant quality taste! I am thrilled with this little machine! Full disclosure I used a separate electric frother pitcher rather than deal with the frothing wand. I prefer not using the steam wand until I am more comfortable with making espresso etc

Great little machine, competitor to Casabrew CM5418
Color: Beige
Compact little espresso machine with enough space under the portafilter for a more normal coffee mug, and a steam wand that doubles as a hot-water dispenser for tea or making Americano. Heats very quickly both for normal espresso and for generating steam. Surprisingly good results going by what I get out of it with a bottomless portafilter and a normal 2-dose basket. Other 51mm portafilters seem to get in with a fair amount of difficulty, you will want some leverage if you try to use a third party portafilter. A slightly nicer machine than the Casabrew CM5418. Additionally I paid about $78 for this machine through a Fat Kid Deals code, which in hindsight means this was a steal of a machine versus the $140 (minimum) Casabrew equivalent. Two thumbs up!

Good, inexpensive espresso machine but NEED TO READ THE INSTRUCTIONS BEFORE USING.
Color: Silver, Color: Silver
I have no financial benefit from this review. After reading negative/positive reviews for this Neretva Espresso Coffee Machine - 1/2 Cups/Frother, I decided to purchase. Although I've only had it since 8/27/25 (writing this review 8/31), I am convinced the bad reviews are because the buyers didn't read the instructions. This was obvious to me because of complaints about the "error messages" and water exiting the steam wand. I was not familiar with espresso machines, and am new at wanting to learn how to brew espresso and other coffee beverages, so had to also look at You Tube videos after reading the instruction booklet that comes with the machine. After experimenting since the machine was delivered, today I was able to make a Flat White. I had several failures using the frother/steam wand. So, there was a learning curve for me. Although I have only been using this machine for 5 days, I am very pleased with my purchase and recommend for anyone who doesn't want to spend more than $100. I would give the warming tray a "D", but everything else an "A". Instead of the warming tray, I pour boiling water in my cup (and empty prior to brewing the espresso), while I'm getting everything ready. The suction cups are very strong, so I decided to put the machine on a small, hard placemat, as it's much easier to move the placemat around than to unstick the suction cups from the counter top to move it around. Also, I needed to purchase a metal pitcher to steam/froth the milk per You Tube videos. Because this is an inexpensive machine and because Neretva does not have a brick/mortar I can call directly, I purchased a 4-yr. warranty. I learned through the internet Neretva has been around since 2008, but it's a global, e-commerce, brand that manufactures and sells a range of small, electric kitchen appliances, mainly through Amazon and Walmart, to consumers who want convenient, affordable appliances for making coffee, bread and a few other foods at home. I have no clue as a consumer how to contact them; hence, the warranty. 9/10/25 Update: I still recommend this espresso machine, but wanted to offer a tip due to what happened to me this morning making my daily espresso. I set everything up to just plug in the machine and press the button before I left for about an hour to do my daily laps in the pool. When I came home, I plugged in the machine and pressed the power button while I took a quick shower. Ten minutes later I was ready for my espresso so pushed the 2 shot button, waited and during what I call the countdown, nothing happened. I did this again, and no espresso came out. Reviewed the Trouble Shooting page. Quickly I realized that the water tank was empty, went through the process again with a full water tank, but the machine did not produce any espresso. Then I removed the Portafilter (which was in correctly) and saw a few coffee grounds on the rim of the Portsfilter (which I hadn't noticed when I got everything ready). I thought "Surely a few grounds wouldn't prevent the machine from working?", but I brushed off the grounds with a very small paint brush I use for this purpose, put the Portafilter into position and VOILA, got my cup of espresso. One might not want a machine that is so sensitive. Okay; I get it. Then spend more money. For me, I'd rather discover the quirks. Just thought this info might be helpful.

Very impressed, perfect shot of espresso with exceptional creme, compact, excellent value.
Color: A-Silver, Color: A-Silver
I am **very** impressed with this sleek, espresso machine. The Casabrews 5418 PRO is phenomenal and such a great value. The pros and cons are very well set out by Neo Pam in her review of December 8, 2025. The machine heats up almost instantaneously and brews a perfect shot and double shot of espresso. It is very easy to use and clean and the instructions are helpful. I really like the compact size. Note that I drink almost exclusively espresso so I make no comment on the steamer other than to say I tested it and it produces copious amounts of very hot steam. Be careful in pushing the wand back--it gets very hot. This was a great purchase and I enjoy it every morning!!
