Pellet-style foods provide greater diversity than fish flakes in terms of diet variety. There are floating pellets for top and middle water eaters as well as slowly sinking types that cater to bottom dwellers.
New Life Spectrum Naturox Large Fish Formula is an outstanding example of an abundant tropical fish food pellet. Packed with highly digestible protein sources like whole fish and krill/squid for natural color enhancement, its formulation features the latest advances in fish nutrition technology.

Floating Pellets
Floating fish feed pellets are designed for fish species that prefer feeding at the surface, such as catfish, goldfish and koi. Their floating properties enable these species to easily locate food while also preventing excess waste accumulation in a pond, thus improving efficiency feeding while decreasing overall feed costs.
Before extrusion of pellets takes place, raw materials must first be ground into an even mixture with a fish feed grinder to enhance diet uniformity and feed quality. Once ground, this mixture can then be softened using steam and water conditioning methods in order to make working with it simpler.
This process also increases starch gelatinization levels to 80-99%, creating floating pellets more digestible for aquatic fish and helping them gain nutrients faster. Furthermore, their floating nature enables farmers to observe and regulate feeding rates more easily.
Sinking Pellets
Pellets differ from fish flakes by being more easily accessible for aquarists to measure how much to feed their fish at one time, making feeding decisions simpler for aquarists and more nutritious than their counterparts.
Pellets may be created through either steam processing to form compacted pressurized pellets (sinking feed), or extrusion process to form expanded floating or buoyant pellets with variable flotation properties to meet specific fish species needs, including size and life stage considerations. The sinkability of a feed pellet is controlled according to its characteristics that best meet your fishes needs.
Sinking pellets are ideal for feeding bottom feeders such as catfish. Their visible appearance helps monitor feeding and water quality conditions in high-density conditions more easily and economically than floating feeds; additionally, sinking feeds require less processing energy while being more eco-friendly than their floating counterparts; they even last longer in storage! Floating feeds may be used when feeding top and middle column eaters as hand feeders may find it easier. Floating feeds also feature easier hand feeder management as well as longer shelf lives than flakes do.
Granules
Granulation is a mechanical process used to modify the physical properties of powders and blends, improving flow characteristics and increasing density while simultaneously decreasing segregation and bridging between particles. Granulation is frequently employed for materials that cannot be processed into tablets due to unacceptable levels of hygroscopicity or other handling issues like poor compressibility.
Alternately, granules can also be made using a more gentle approach in which powder mix is squeezed between counter-rotating rollers to form a compressed sheet and cut by a cutter into individual granules – this usually results in smaller-sized granules than produced through dry mixing.
Some granules are designed for delayed release and coated with gastro-resistant material to resist degradation by stomach acids – these are called enteric-coated granules – while other varieties dissolve quickly when exposed to water, known as effervescent granules.
Flakes
Thera+A is an outstanding, slow-sinking pellet designed to bring out vibrant colors in tropical fish. Packed with protein and salmon skin rich in beta-carotene – which acts as a color enhancer when fed to aquatic life – as well as essential nutrition such as spirulina, chlorella and seaweed for all bottom dwellers, Thera+A is ideal.
Flakes are usually composed of animal and plant proteins designed to replicate a fish’s natural diet as closely as possible, although some brands cater exclusively for certain species such as goldfish or cichlids to enhance scale strength and color enhancement.
Some flakes are freeze-dried to maintain freshness and provide small top feeder fish such as neon tetras with an opportunity to consume food at their own pace, without pellets or granules clumping together in their stomachs. Other varieties are specifically designed to float, making them accessible to any type of fish.
