When your pet fish food runs out, there are plenty of other healthy options you can feed them. Some of these alternatives are surprisingly nutritious and will give your fish the protein and essential vitamins and minerals they require to thrive.
Some of the healthier alternatives to meat include vegetables, fruits, eggs and earthworms. All of these come from natural sources and provide essential vitamins, minerals and nutrients.

Vegetables
Tropical fish species tend to be herbivores or omnivorous, so adding vegetables to the aquarium is one of the best ways to keep them healthy. Vegetables also provide important dietary minerals like selenium and zinc.
Vegetables make a great alternative to fish flakes or pallets and tend to be easier for tropical fish to digest. Try boiling or blanching them beforehand so they’re easier to swallow.
Herbivorous fish are especially fond of green leafy vegetables such as lettuce, spinach and zucchini. However, you must remove uneaten vegetables from the tank after 12 hours in order to prevent polluting the water with pollution.
Fruits
Herbivorous fish can eat a variety of fruits. Bananas, mangoes, pears and watermelons are just some of the foods you can feed your tropical fish.
Fruits can also provide a natural source of calcium for your fish, though it’s best to monitor their diet closely as too much sugar could lead to an algae bloom and other issues.
You could also try some other options, such as boiled or steamed green vegetables. These are beneficial to many herbivorous tropical fish species’ digestive systems.
Eggs
Eggs make for an excellent tropical fish food due to their low fat content and high protein content. Furthermore, they’re packed full of essential vitamins and minerals like Vitamin A and thiamin.
Eggs can also be fortified with vitamin D, which is essential for strong bones and teeth. A medium egg contains 0.9 milligrams of vitamin D in its yolk alone – all of which is stored as energy.
Hard-boiled egg yolks can be given to your fish as an occasional treat, but be mindful not to overdo it. Leftover yolks will rot in the tank, leading to cloudy water conditions.
Fish Filet
A fish fillet, from the French word filet meaning thread or strip, is the flesh of a fish that has been cut away from its bone by cutting along one side parallel to its backbone.
When filleting fish, all scales should be removed and the contents of the stomach carefully detached from the fillet. Since these don’t contain larger bones running along vertebrae, fish fillets may be referred to as being “boneless.”
Rice
Rice is an abundant grain grown around the world and a staple of many cultures. It provides sustenance to over half of humanity, mostly in Asia and sub-Saharan Africa.
The plant is a monocot that can thrive as either an annual or perennial crop, depending on its environment and growing conditions. Generally, this monocot requires high average day temperatures but cooler nights to thrive.
Rice can be grown either dry or in flooded areas, known as paddy fields. It may also be irrigated using an artificial water supply.
Earthworms
When searching for an alternative tropical fish food, earthworms could be worth considering. Not only are they packed full of protein, but also contain essential nutrients like iron, amino acids, calcium, copper, manganese and zinc that make them great food sources.
Earthworms can improve the quality of your fish tank by reducing pollution. Furthermore, they provide essential fatty acids. You may feed them to your fish once or twice a week depending on which species you have.
