Live fish food – a delicacy or a necessity?

Beginners frequently prefer to feed their aquarium pets dry food rather than live food. The fact that they do not have to think about where and how to store it correctly, monitor its quality, or clean it before giving it to the fish eliminates a lot of the stress.

Live food, on the other hand, is the most beneficial for fish because it has not been processed and therefore has retained all of its beneficial properties. To be sure, under natural conditions, small invertebrates make up the majority of the diets of all fish species, and live food is usually the primary source of nutrition for predatory species as well. As a result, if you want your aquarium fish to be large, healthy, and beautiful, you must ensure that they are fed live food on a consistent basis.

Benefits of live food include:

  • Live products contain an adequate amount of high-quality protein, which is easily absorbed by the fish;
  • Thanks to capturing mobile larvae, the fish preserve their natural predatory instincts;
  • Only moving objects are perceived as food by fish fry and certain predatory fish species.
  • With proper use, the water after using live food spoils to a much lesser extent than dry food;



Fresh bloodworms are easily identified from stale bloodworms by their vibrant red color, mobility, and distinct odor. Moths (mosquito larvae) Bloodworm is especially popular in the summer, though it isn’t completely gone in the winter. Small schooling fish and carnivorous fish equally enjoy eating it.

When purchasing bloodworms, look for larvae that are less than a centimeter long. Make sure the heap does not contain any dark maggots. Move the moth around with a stick to see if the larvae are actively moving; if they aren’t, the food isn’t fresh and isn’t worth the money.

It is preferable to buy food from a trusted source, as this will protect you from a variety of unpleasant surprises. Even a very fresh sizeable bloodworm can be poisonous to your fish if it was captured in a toxic environment. Synthetic fertilizers from agricultural fields are sunk into or near reservoirs, causing this.

Consider purchasing the bloodworms in small amounts and try to keep them alive for as long as reasonably practicable. If you’re not sure if the feed is bacteriologically clean, keep the larvae in a glass of water for a couple of days, changing the water 2-3 times per day. You’ll get rid of as many bacteria as possible this way, lowering the risk of disease in the fish tank noticeably.

After such “therapy”, the bloodworm should really be washed and stored in the prescribed sequence. Spread the live food in a thin layer on a plate with a clean, water-soaked paper or cloth (up to 1 cm). Using another layer of paper or cloth, cover the larvae. Use the refrigerator’s bottom shelf for storing. Make sure the bloodworm is almost always humid by hydrating it with water every now and then.

Bloodworms should never be overfed to the fish, as this can cause bloating. Overfeeding on a regular basis may result in disease development and the mortality of aquatic dwellers. Also, make sure the moth does not drill into the soil’s foundation; if it does, the fish will be unable to reach it, and the dead larvae will cause the soil to rot.

Sludge worm

Sludge worm is even more nutrient-dense than bloodworms, and it is loved by almost all fish. However, you must only consider giving it in small amounts, or your “animals” will gain weight. If you have young rays, discus, or malnourished fish in your aquarium who need high-calorie food with high protein content, this food will become indispensable due to its high fat and protein content.

Keep in mind that a healthful sludge worm is a light pink in color when purchasing it. The worms constantly fidget in the water when you move the “pile”, which causes it to contract strongly. Sludge worms are notable for their ability to survive for extended periods of time when properly stored (up to a month or more).

A large circular bucket with a flat bottom is ideal for storing this type of live food. Place the worms at the bottom of the bowl and fill it with just enough water to cover the bottom layer. Place the dish in a chilly, dry place in which the temperature does not exceed +10 °C (for example, in refrigerators or in the basement). Under running water, rinse the sludge worm twice a day.

It must be kept in clean water for at least a week before being fed.

You can clean it yourself in a short time. 2 tablespoons of soy milk should be poured over sludge worms in a dry dish. Within a day, the worms will have consumed all of the soy milk, causing the organic material in their intestines to be completely removed.

Other methods for disinfecting live food exist, the most effective of which is ozonization.

You can either cut the maggots in half or separate some specimens from the stack if you need small live food to feed the fry. To do so, run a strong stream of water over the trays. The worms will separate and float up as a result of its influence. The large representatives are then pushed to the bottom, while the small representatives are kept on top. It’s only a matter of draining them into a different dish.

As live food, small crustaceans

Small crayfish like daphnia and artemia, both of which can be grown at home, are also popular live foods. This is a significant advantage because this feed is pathogen-free, making it the safest of all live feeds.
