We’re often asked why Vitalis pellets sink rather than float on the water surface. This is very specifically by design. To put it simply, it’s much better for the fishes’ digestive systems and promotes a more natural feeding habits.
The processes we use to make our fish pellets are unique to us as we design and build our own machinery to achieve a pellet product like no other on the market. Traditional techniques, such a twin screw cooker extrusion, use high temperatures to sterilise and process the food, often leading to a floating pellet that contains pockets of air. Instead, we use cold extrusion techniques which mean that all of the nutritional value of the raw ingredients is retained within the food.
These techniques allow us to create a soft, malleable pellet that is attractive to and easily digested by the fish. The texture and consistency of our fish pellets also means that we are able to produce it in larger sizes to cater to larger species in public aquariums, as well as in the form of our Marine Strand which is designed to feed the more challenging animals such as large sharks.
When it comes to the Vitalis pellets used in public aquariums, we offer a range of sizes designed to best suit the fish being fed, considering not the size of their mouths, but the size of their throats. If a fish swallows a pellet too large for it to easily swallow, it has to break it up, resulting in loose particles entering the water and affecting water quality. Swallowing the right size pellet means that all of the nutritional value is consumed, easily digested due to it’s soft nature and this in turn has a significant benefit on water quality and filtration systems.
