There are different opinions among fish enthusiasts as to whether floating or sinking pellets is the better type of fish foods given to your pet.
Floating Fish Feed Pellets are more expensive to buy and more expensive for feed millers to manufacture. Floating pellets (also known as expanded or extruded pellets) require to go through an extrusion process during processing. This section of a feed mill is most of the time costly to set-up and run than a standard pelleting section.
They are usually used in larger underlings, 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. This enables you to observe your fish each day, which helps in monitoring their health and vigor. Also you can adjust the amount of feed per day and avoid wasted feed and pond pollution problems
While there is still some debate, floating feed is still prefered in some cases. And although it is more expensive you can reduce feed costs and still have the advantage of observing your fish by mixing 15 percent floating feed with 85 percent sinking feed.
Sinking Fish Feed Pellets also know as a hard pellet, are more economical. Sinking feed will have water stability of up to an hour, and will gradually sink and settle on the bottom if uneaten.
Since ingredients are pressed togetherm it makes it impossible for the fish to selectively eat the ingedients they want. Sinking pellets are adapted to mechanical feeding and can be handled considerably without deterioration. Sinking pellets are sometimes used in winter when the fish do not regularly surface. Also by pelleting some feeds it can be avoided to harm some ingredients which do not like the extrusion process.
Different fish feeds are suitable for different kinds of fishes. For making floating fish feed, Fish Food Pellet(Floating Feed) Making Machine manufactured by Longer Machinery adopts auto-temperature controlling system which making it more precise and viewable to control the temperature. Fish food made by this pellet extruder is of puffing type more easily to digest for fishes.The fish feed pellet size can be from 0.9-10mm to feed different sizes of fishes.The puffing fish feed pellets can float on the water surface without dissolution for over 12 hours.
