Aquarium fish typically spend much of their day searching or hunting for food, ranging from browsing to predator-hunting to carnivory; depending on their species they may require both plant and animal proteins for sustenance.
Fish should only be fed the amount they can consume within one sitting; any leftover food may sink to the bottom and decompose, potentially harming aquarium water quality and decreasing its quality.

Danios
Danios are highly active, social fish that flourish in community aquariums. They do best when kept in groups of five or more and will often be seen darting around, chasing each other or playing “tag” with other fish. Danios exhibit sexual dimorphism with males exhibiting more vibrant color while females have rounder bellies; males should be kept with females at a 1:1 ratio to avoid aggression from aggressive males; also, tight fitting lids on tanks will prevent any accidental escapees!
Danios are opportunistic eaters that consume plants, algae, zooplankton and small invertebrates in the wild. When kept as pets they should receive a varied diet that meets all their nutritional needs; since they can become susceptible to certain aquarium diseases regular water changes and filters should be done as soon as possible to avoid future complications. Celestial pearl danios or galaxy rasboras are an excellent addition to the family and provide an ideal option for planted aquarium environments
Freshwater Flakes
Fish need a balanced and nutritional diet in order to thrive and showcase their beautiful colors, and flakes provide an easy and affordable way to supplement top feeders’ feeding regimens.
These foods come in different formulations to meet different feeding habits: floating, sinking and pellets. Pellets, micro-pellets and granules tend to sink to the bottom of an aquarium and are relished by catfish, loaches, and other bottom dwellers.
Feed your aquarium fish no more than they can consume in about 10 minutes at each feeding. Overfeeding can clog the filter, create foul odors in the water and even produce toxic waste that poison fish. Telltale signs of overfeeding include cottony white fungus growing on decorations or substrate, increased ammonia/nitrite levels and cloudy aquarium water. Use a siphon or gravel vac to quickly and safely remove any leftover food or any leftover flake pellets after each feeding to avoid overfeeding altogether.
Algae Wafers
These sinking discs were specifically created to meet the feeding habits of plecostomus and other algae-feeding bottom feeders, including plecostomus. Their design contains more vegetable matter than standard fish food to provide your herbivorous fish with all of the nourishment they require. Their disc shape also allows less aggressive species access over an extended period of time without it dissolving and clouding up their environment.
This food makes an excellent supplement to fresh or live plant growth, sunken fish food or any other natural sources in your aquarium. However, it should not be used as the sole diet source due to not providing all of the essential nutrients required for balanced nutrition.
Ideal for both freshwater and saltwater herbivores, this high-quality food features an all-natural blend that promotes digestion while preventing waste buildup in an aquarium. Furthermore, Tetra’s patented ProCare formula of vitamins and Omega-3 fatty acids offers additional immune boosting effects, protecting against stress and disease.
Super Green
Super green is a gel-based fish food made up of spirulina algae (or another green alga) which provides excellent daily nutrition to plecos, African cichlids and many other herbivorous aquarium fish species. Furthermore, super green food products are great for bottom dwelling snails as it contains various vitamins, minerals and other important nutrients that promote health in water environments.
Though these foods should not be fed to fish daily in freshwater and saltwater aquariums, they can provide a useful supplement. It is wise to have two or more types of food on hand so as to provide both daily feedings as well as emergency backup.
Keep in mind that some so-called super greens contain high energy levels derived from krill. This will need to be managed if you keep freshwater lionfish or Arowana which require lower energy levels than typical. Instead, opt for something such as AAP Clay Neighbor’s Custom Fish Food or AAP Spirulina 20 Flake which have both been around and optimized (this is what I use myself).
