Microbe-Lift MLLSPMD Sinking Fish Food Pellets for Ponds, Water Gardens, and Fountains, for Live Goldfish and Koi, 3 Pounds

My goldfish and especially Koi have grown considerably within a month of switching to this food! They love it and get into a feeding frenzy and finish all of it before it sinks to the bottom. It is the size of black pepper seeds which is perfect for my fish. It sinks fairly slowly. In fact, a few pellets always float till they get fully wet. Overall excellent product.

It sinks while triggering a feeding frenzy. If you want to watch them eat, I recommend feeding your fish half a teaspoon or a teaspoon (pinch) at a time; otherwise, most of it will sink to the bottom.

This is a useful formula, sinking down for my smaller pond fish. I use another larger floating food for koi and the larger goldfish in my outdoor pond. But these are very small pellets and I wish they were larger. Deducting a star because they are overpriced for the amount that you get.

It was tough to find good high quality sinking food for those koi and hi-fin sharks in my pond that won't come to the surface. Most koi food seems to be the floating type. I actually mix this in with some floating food and get a 50/50 mix. That way the bottom loving fish can still get their fill too. Now my pond is a swimming pool for fish so I don't have rocks or plants in the bottom. This mean sinking food does get all eaten. Another positive point is this food did not cloud the water at all - of course it never lasted that long anyway since the fish really liked the flavor. You might want to keep that in mind if you get this food since if you have rocks or plants sinking food might not be best. Still, I like the ingredients and high quality of this food and will be ordering more.

My large koi fish love it!

This food has been valuable in feeding one of our koi that has trouble getting to the surface to eat. I have had no problem with it sinking to the bottom when I soak it in a jar of water for five minutes before feeding. My other koi enjoy it also, once they have finished their floating food and after the compromised koi has had his fill. No problems with it clouding my pond's water, either.

I am appalled. The bag I bought last year sank just fine. The one I just bought doesn't want to sink at all. I have to throw it down very hard to get it to go below the service. What really stinks is that there are very few other options on the market so I am stuck dealing with this product.

Needed a food for my koi that I could feed without training them to come to the surface - the raccoons wiped out our previous population and I think the fact that they had learned that food would be there at the surface whenever there was movement there. (For ten years I had fed a food that floats.) I lost 13 koi in two nights and I figure they just served themselves up. Some were well over a foot long and having had them for ten years I was devastated. I replaced seven of them this Spring and have been feeding ONLY this since. As advertised, it sinks immediately so that my koi have not acquired the habit that I used to enjoy (but now realize was the basis of their demise) of coming to the surface to greet me. Instead, the six I have now cruise the bottom excitedly, waiting for their food which sinks promptly - and they've grown from a couple of inches to 8 inches plus! Very happy with this!
