Floating Fish Feed VS Sinking Fish Feed
Nowadays there are many fish farm to feed catfish, goldfish, koi, and other kinds of fishes. There are two types of fish feed pellets for choice: floating fish feed pellets and sinking fish feed pellets.
But sinking vs floating fish food, which kind of pellets is better for koi fish and goldfish? Generally speaking, for different kinds of fishes, we feed them with different types of feed pellets. Each of these two different types of feed pellets has advantages and disadvantages.
Sinking Fish Feed Pellets: Features and Requirements
1. Species Adaptation and Biological Risks
For some ornamental fish like goldfish and koi, sinking vs floating fish food, generally sinking fish feed pellet is better for them. Because goldfish being a greedy pet will usually dash and swim towards their food and during the commotion while grabbing the pellets, they will end up sucking air into their stomach as they gulp their meal.
Usually what you can observe is that air pockets will get trapped in their poo discharge and prolonged condition are sometimes blamed as the cause of flipping disease seen happening on goldfish. Therefore use only sinking food pellets for your goldfish.
2. Physical Properties and Management
Bottom feeder shrimp prefer sinking pellets (density greater than that of water, 1 g/cm3) and will not accept a floating feed. The farmer can estimate feeding rates according to the growth in his pond, which can confirm feeding whether too low or too high than the actual requirement.

Floating Fish Feed Pellets: Features and Performance
1. Monitoring and Health Management
Floating fish feed pellet are usually used in larger fingerlings, food fish and broodfish. Floating on the surface of the water (usually maintaining integrity in the water for several hours), the fish must come up to the surface to eat.
The farmer can observe their fish each day, which helps in monitoring their health and vigor. Also they can adjust the amount of feed per day and avoid wasted feed and pond pollution problems.
2. Nutritional and Textural Advantages
Floating fish feed pellet may contain more fat than sinking feed pellet because too much fat causes the pellets to fall apart. Higher fat means higher calories, which is a benefit for many categories of fishes, including hard feeders and performance fishes with higher energy requirements.
Fishes that are not used to floating fish feed pellet may take a few days to become familiar with the lighter, more breathable texture. Other benefits of floating fish feed vs sinking feed include:
- Lower contamination
- Longer water stability while maintaining all of its nutrients
- Higher digestibility
- Greater efficiency and higher conversion rates

Case Study: Goldfish Buoyancy and Feeding Habits
When it comes to goldfish, floating fish feed vs sinking fish feed, sinking or floating pellets for goldfish? which is better? the scene is quite different. There is some disagreement among experts as to whether it is better to feed floating or sinking pellets to fish.
But basically from my own experience it’s best to use the submersible kind, because goldfish are a voracious pet and usually rush for food, and in the fuss of grabbing grains, they end up sucking air in their stomachs. When they eat a big meal. What you can often notice is that the air sinuses get trapped in their faecal secretions, and the prolonged condition is sometimes blamed on the goldfish’s buoyancy problems. So my advice has always been to use strictly soaked food pellets for your goldfish.
However Unless your goldfish are sick or sensitive to buoyancy problems, both floating and sinking food will do just fine. If you have sensitive fancy goldfish, I highly recommend soaking dry food before feeding. Dry food expands as it absorbs water. If your goldfish eats a pellet before it expands, intestines may get clogged.
Technical Comparison: Advantages & Disadvantages
| Feed Type | Advantages | Disadvantages |
| Floating Feed | 1. Waste reduction 2. Convenient observation 3. Reduction of diseases 4. Improves Feed Utilization 5. A Wide Application Prospect | 1. more expensive to buy floating fish feed 2. equipment more expensive for manufacturing floating pellets |
| Sinking Feed | 1. more economical 2. easy to manufacture | 1. water stability of less than an hour 2. cause water pollution in long run 3. better to feed in winter when fish come out of water |
Decision Making for Farmers
Floating fish feed vs sinking fish feed pellets? some people prefer fish feed pellet machine to make floating pellets,because they not only can their fishes, and enjoy hand feeding, but also because they can see what is happening to their food.
They worry a bit about with sinking pellets at the bottom of the water, but we can not only just for checking our fishes and enjoy our hand feeding, we should think about our fish features and live habit.
