Review: Pellets as dense as the muscular koi mascot! - I was disappointed that my first order got lost in transit and never made it, so I had to wait even longer amid the pandemic for a second order attempt. I do not fault the seller for this so I will not remove a star for something that is outside their control. I'm rebooting my pond with three koi I've had a couple years and 8 young koi I plan to grow out. The 8 young koi went through quarantine before I introduced them into the main pond. In the meantime, when I finally got this food I used it to help put some size and weight on the young ones and that it did in the two weeks I had this food (halfway through their quarantine). After feeding the first time I realized that this pellet is extremely dense, it falls straight to bottom—which is fine, I like that the koi can use their foraging behaviors—and it takes them a little bit longer to chew and takes way less of it to fill them up. So feed very lightly and build up more if necessary for your fish until you figure out how much you can give them per feeding. Like I said, it takes my young koi a while to chew the pellets before they go back for more, but the pellets do hold up for quite a long time. It has never once fouled my water, in fact, my parameters (ammonia/nitrite/nitrate) are a wee bit healthier than when I feed them their usual floating pellets. I liked the packaging, particularly the muscular koi mascot, it reminds me of something I would see here in the countryside of Hawaii. I liked the protein content since growing out fish requires high amounts of protein among other things. I was so eager to try this food out. It comes with a nice ziploc-type seal so you can just use the bag. However, I use the extra precaution of putting it into a gallon ziploc bag and refrigerating because of the humidity here, it tends to spoil things quickly. The price of this food is kind of high, but I think the quality puts that within reasoning. Especially because you don't have to feed much. I use this as part of a rotation with another type of floating pellet, steamed egg, repashy, and the occasional boiled sweet potato chunks. I've had the food for about a month now and it has already proven at least that my koi love the stuff and are growing quickly. From the time I got this food I'd say the young ones have put on an average 1.5", and certainly some girth around the shoulders and tail. Not bad for a simple backyard pond! Oh, and my other three koi I've had for a couple years previously have definitely beefed up in size and length as well! Something I haven't seen much of in the past couple years I've had them. All-in-all, I have absolutely zero gripes with this food and no reason to remove any stars for this rating.
Review: great for fish with Wens - high protein food with unique proteins, while pricey, it works very well. If you are trying to grow "wen" on a fish this gets significant growth in 2-3 weeks. I store mine in the frog sense the protein content is so high.

### ⭐⭐⭐⭐⭐ Great Product/Poor Packaging
*by L***E on April 30, 2024*

This is very very palatable to the fish. I am currently adding this to food I already feed as an extra boost. Would say pertaining to the picture I have attached. Great product poor packaging, thank goodness it was also in an Amazon packaging and I did not lose any product.
