By including vegetable matter in their diet, adding it will help ensure they remain vibrant, colorful and healthy. Many tropical fish species are opportunistic feeders who will consume whatever is provided them.
Feed them only a small pinch at each feeding and monitor their response. If there’s food left over several hours later, that indicates an overabundance.

Dry Food
Many fish species require dry foods in various forms for sustenance, most frequently in flakes form; however, these also come in pellet form that floats, slowly sinks or rapidly sinks; there are even options designed specifically to meet certain species needs; pet stores often sell dried spirulina or nori algae sheets which herbivorous fish enjoy nibbling on; these sheets may help lower risk of swim bladder disorders or bloating in these fish species.
Some omnivorous or carnivorous fish will also enjoy eating vegetables like peas boiled and crushed into bite-size pieces for them to swallow easily. Be cautious of overfeeding this source of nutrients since fish typically have very small stomachs which cannot extract as many essential vitamins from vegetable matter.
Learn your fish’s dietary needs, and feed it accordingly. Carnivorous species need more protein than herbivores; aim to give your carnivorous fish their food at approximately the same time every day at about their designated feeding time – being mindful not to overfeed as this could reduce water quality and eventually kill your fish!
Frozen Food
Frozen fish foods provide the next best alternative to live food. Their balanced mix of proteins, fats, vitamins and minerals mimic a fish’s natural diet in its wild habitat. Frozen options may include flakes, granules, wafers and tablets that float slowly or quickly and may even be tailored specifically for individual species of fish. Some pet stores sell sheets of spirulina or nori algae that herbivorous fish can nibble at.
Avoid feeding your fish any cooked or processed food, which may be too difficult for their digestive systems to break down and can cause bloating, swim bladder disorders or other health issues.
Guppies, gouramis and angelfish may enjoy nibbling on boiled egg yolk or lightly steamed vegetables as part of a balanced diet; however, these should only ever be offered occasionally as treats or supplements to their usual foodstuffs. Betta fish or pufferfish tend to enjoy nibbling frozen bloodworms for added protein intake!
Live Food
When fish food flakes run low, there are various alternatives such as live foods like brine shrimp or bloodworms which should only be fed sparingly; otherwise they may contain high levels of fats and oils which pollute aquarium water.
Some tropical fish that feed both omnivorously and herbivorously enjoy snacking on raw vegetables like spinach or carrots chopped into very tiny pieces for their consumption by smaller tropical fish. Furthermore, herbivorous tropical fish can also ingest algae, providing another healthy food option.
As it can be easy to overfeed fish, only feed your carnivorous varieties enough food within five minutes for digestion. Look for fish food with higher protein content when shopping; carnivorous fish typically require higher amounts.
Supplements
Fish are capable of living for long periods without food, depending on factors like their species and size/age. But don’t panic! There are still options you can turn to in an emergency when your supplies run low if needed.
Most fish enjoy eating boiled rice and pasta, along with other boiled foods like brussels sprouts, cucumbers, zucchini, and carrots. Small fish and shrimp especially enjoy hard-boiled egg yolks as a special treat!
Bloodworms, daphnia or infusoria can also be purchased at aquarium stores to supplement the diets of both herbivorous and omnivorous fish species. While these alternatives should not be fed regularly as primary nutrition sources, feeding your fish a little of this food every evening before bedtime gives their digestive systems time to process the foods efficiently overnight.
