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

Sometimes it takes a few seconds at most a minute but they do sink .

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!

My fish love this food and they are growing so fast.

99% of the pellets float on the surface. They end up getting pulled into the filter before they have a chance to sink or be eaten. I've thrown some into a bucket of water to see if they would eventually sink and 30 minutes later they're all still floating. The fish will eat them, but just not fast enough before they go into the filter. Wish they sank as advertised - I will not buy these again!

Tried them as minnow bait. They float away.

This is a good product for feeding those fish that just hide all day near the bottom. Medium sized pellets so you will still have to use flakes for smaller fish because these are pretty hard. Not all of them sink which is good or bad depending on what you want.

I am so impressed with this company. They responded very quickly to my question and were extremely helpful with their response. The quality of the food is top notch and having it sink really helps my younger koi/goldfish which hesitate coming to the surface to compete with the big koi. Thank you Microbe-Lift!!!

I bought this fish food because it says it sinks. Sadly nothing sinks. However, the fish love it. But it does not sink
