How to Feed Your Tropical Fish?

The process of feeding your tropical fish starts with identifying the kind of food to give them. The options include dry foods, live meals, and freeze-dried foods.

One conflicting area when it comes to feeding tropical fish is the daily amount to give your aquatic pets. The prevailing advice seems to be to underfeed instead of overfeeding. Wild fish do not eat at specific times, and they will continually graze for food in their surroundings.

Aquarists who intend to mimic the natural habitats will feed their pets up to five times a day. Feeding your pets once a day is the minimum, and most aquarists prefer to do it twice every day.

Feeding tropical fish is as easy as sprinkling in your choice of food, and ensuring you give them only the amount that they can finish in five minutes.

If you have a community tank, watch the residents eat to ensure all of them get enough. If you notice any leftover food, you may be overfeeding the species.

You may need accessories to ensure slower fish get their share or to make the process less messy. Such accessories include automatic feeders, which function off a timer that you can set when going to work. The feeder can either have a series of hoppers or a single hopper to dispense food at set intervals.

Feeding tongs are also commonly used to hand feed fish. They are particularly handy in training predatory species that do not respond to nonliving items as food.

You can use the tongs to wiggle food in front of the fish to mimic prey movements.

You can also use feeding rings to feed your fish as they keep floating meals in one area. Some rings float freely, and others attach to the tank’s glass via a suction cup.

Feeding rings are ideal for peaceful community tanks where the species feed well together. They will reduce mess, but it is best to let the food to float freely in less peaceful setups.

If you want to give your fish live tubifex worms, you can use worm feeds that have holes for the worms to pass through.

It is common for fish to start begging for food once they get comfortable in their environment. You may see them on the surface waiting to be fed, but you should avoid giving in. Underfed fish can be identified if they fight one another during meal times.

After a couple of minutes have passed and your fish have stopped eating, it is a good idea to rid your tank of uneaten meals. Leftover food will only dirty up your aquarium and support the growth of bacteria.

Why You Should Avoid Overfeeding Your Fish?

It is easy to overfeeding fish, especially if your fish always come up at the surface ready for food when they see you approach. Overfeeding, however, has many serious consequences, including:

  • Cloudy and Dirty Water – Overfeeding leaves organic waste in your tank that will soon begin rotting. If you are particularly keen, you should be able to see leftover meals at the bottom of the tank. Overfed fish will also produce a lot of waste, which will quickly accumulate in your setup. Your aquarium will subsequently begin to smell and have cloudy water. Water changes are necessary at this point to eliminate waste.
  • Algae Growth – Fish waste and the rotting leftover food support algal growth by releasing ammonia, nitrates, and phosphate. An algae boom leaves your tank looking green and unsightly, and it is hard to get rid of it entirely. Algae is known for overrunning an aquarium very quickly and being a headache for aquarists.
  • Low Oxygen Levels – Leftover food uses oxygen in the anaerobic process and releases carbon dioxide. This leaves little oxygen for your fish and the aquatic plants you have in the tank.
  • Mold and Fungus – The organic material left in the aquarium will also promote the growth of fungus and mold. The presence of these elements is especially critical if your fish have any open wounds or fin damage. The subsequent infections will spread quickly in the tank and result in fish kills if unchecked.
  • Pest Snail – Pest snails are a common concern with aquarists. While they are mostly brought about by aquatic plants or water, their population increases rapidly if there is uneaten food in the tank. A food surplus will lead to a pet snail bloom that is hard to eliminate. Fish owners will typically reduce feeding to combat the pet snail problem.
  • Ammonia and Nitrates – Every aquarist knows the danger of having levels of ammonia and nitrate in fish tanks. These elements are toxic if allowed to build up, with the problem worse in smaller tanks. Ammonia is especially deadly, and it will kill your fish quickly.
  • Low PH Levels – Acids are typically produced as the organic material breaks down in the aquarium. Some fish species are sensitive to PH levels, and the drops may impact them negatively.
  • Blocked Filters – Filters perform an exemplary job of filtering the dirt out of aquariums. If leftover food buildup, however, the filters will become overworked and clog up.

What to Feed Your Fish When Out of Food?

Do not panic when you discover that you are out of store-bought fish food because they are plenty of DIY options for any aquarist.

Green leafy vegetables make ideal emergency fish meals, and all you have to do is cut them up in small pieces. You can use lettuce, spinach, brussels sprouts, zucchini, and cucumbers.

It is advisable to boil the greens to make them easier to digest. You can also give your fish small pieces of rice and pasta. Hard-boiled egg yolks are good options for smaller fish and shrimps.


Every fish-owners wants to give their pets a balanced diet to strengthen their immune system. There are varieties of flakes, pellets, wafers, and freeze-dried meals you can get from pet stores, depending on the nutrition requirements of your fish.

Experienced aquarists will warn you about the dangers of overfeeding, which is easy to do because fish will sometimes not know when to stop feeding. When in doubt, it is always better to underfeed.
