Fish foods come in various forms and most contain a blend of foods designed to provide all necessary nutrition. Some formulas may even boast greater nutrition.
Many fish owners tend to overfeed their aquatic friends. A general guideline is to give only as much food as your fish can consume in one minute or less.

Dried Food
Fish food alternatives can provide temporary solutions when your supply runs dry, though many do not contain all of the essential vitamins and nutrients for tropical fish to thrive.
Flaked food made of dried meat may provide enough nutrition for carnivorous fish but may not meet the needs of herbivorous and omnivorous species. You could try feeding frozen water fleas (daphnia), brine shrimp or chopped vegetables like lettuce and peas to these species instead.
When feeding this type of food to your fish, remember that overfeeding is easier than underfeeding; only give your tank enough food for consumption in five minutes and remove any leftover food within 48 hours or it will spoil.
Frozen Food
Many tropical fish enjoy extra treats between regular feedings. Some varieties prefer fatty food sources like shrimp and crabs while others thrive on green vegetables and protein sources – most aquarium species being omnivorous in nature.
Frozen food options for fish include flakes, pellets, sinking or floating food and specialty formulas tailored specifically to each species. Pet stores also sell frozen spirulina cubes that herbivorous fish love nibbling on.
Alternative foods for aquarium fish might include daphnia (water fleas), edamame, krill or bloodworms – high-protein sources with limited carbohydrates – for short-term feeding purposes.
Some aquarium owners feed their aquarium fish boiled egg yolks as an excellent source of protein for smaller species, although excessive egg fat may become constipating and lead to digestive issues in fish. Vegetables may also be beneficial; simply boil them first until soft before breaking up into small pieces for feeding to your aquarium fish.
Live Food
Tropical fish usually need a well-balanced diet consisting of flakes, frozen food and live food; alternative diets should only be used occasionally and not as replacements for their prescribed meals; excessive use can be harmful to water quality or even be toxic to the fish themselves.
If you’re leaving on vacation, make arrangements for someone to feed your fish. Provide specific feeding instructions, and adhere to the rule that only feed enough for five-minute consumption – overfeeding could damage or cause waste build-up in their tank.
Some tropical fish seem to prefer fresh, living food over prepared foods; this may simply be habit, and most can be weaned off of live feed within a short time period.
Supplements
Supplements can help ensure that your fish receive all of the vitamins they require to remain healthy in an aquarium environment.
Supplementing your fish’s diet with vegetables is a simple way to ensure they receive all of the necessary nutrients. Most aquarium fish species are herbivorous or omnivorous and will consume most vegetables; herbivorous fish typically prefer eating lettuce and cucumbers while bottom feeders like plecos may prefer larger items like zucchini or sliced carrots as bottom feeder food sources.
Many pet stores sell frozen fish food blends tailored specifically to specific aquarium fish types such as community or cichlid fish. By purchasing one of these blends, they can help save you the hassle of having to use other forms of food when your aquarium runs low on food. But be mindful that any time you add something new into the tank, be it food or otherwise, you must ensure it has fully cycled first before adding new feed.
