What is an aquarium fish feed
Aquarium fish feed is plant or animal material intended for
consumption by pet fish kept in aquariums or ponds. Fish foods
normally contain macronutrients, trace elements and vitamins
necessary to keep captive fish in good health. Approximately
80% of fishkeeping hobbyists feed their fish exclusively prepared
foods that most commonly are produced in flake, pellet or tablet
form.Pelleted forms, some of which sink rapidly, are often used
for larger fish or bottom feeding species such as loaches or
catfish. Some fish foods also contain additives such as sex
hormones or beta carotene to artificially enhance the color of
ornamental fish.
There are two types of foods for fish,
1. prepared foods
2. Live foods
What are prepared foods,
Prepared foods are those foods that are non-living
and are made by the aquarist or bought already prepared for
consumption for fish.
What are Live foods,
Live fish food include earthworms, sludge worms, water
fleas, bloodworms, and feeder fish. Food for larvae and young fish include
infusoria (Protozoa and other microorganisms), newly hatched brine shrimp and
microworms. These are the most preferred type of food for fishes, but are difficult
to get. However, freeze dried forms of earthworms, tubifex etc. are available now
Prepared foods
Dry foods,
Flake food is a type of proprietary or artificially manufactured
fish food consumed by a wide variety of tropical and saltwater
fish and invertebrates. It is ideally suited to top dwellers and
mid-water fish though numerous bottom dwelling species
consume flake food once it has settled on the bottom. Flake
food is baked to remove moisture, ensuring a longer shelf
life.Generally the more moisture a particular example of fish
food contains, the more readily it will deteriorate in quality.
Dry foods are also available as pellets, sticks, tablets, granules,
and wafers, manufactured to float or sink, depending on the
species they are designed to feed.
Vacation food,
Vacation foods, also known as "food blocks" (or "weekend blocks"
for smaller versions), are designed to be placed inside theaquarium to forgo feeding while the owner is absent. These
blocks release small amounts of food as they dissolve. Food
blocks can be a good choice for smaller tropical fish, but can
pollute the water if the tank is neglected for too long.
Medicated fish food,
Medicated fish food is a safe and effective method to deliver
medication to fish. One advantage is that medicated food does
not contaminate the aquatic environment and also, unlike bath
treatments, does not negatively affect fish, filtration and algae
growth in the aquarium. The parasites will get treated spot on
by medicated food, because the fish is ingesting it
Freeze-dried and frozen fish diets,
Freeze-dried and frozen fish foods were primarily developed for
tropical and marine fish and are useful in providing variety to
the diet or specialist feeding needs of some species.These
include tubifex worms, mosquito larvae, bloodworms, water fleas
along with brine shrimp.
Frozen fish food,
Perishable food can be preserved by frozen storage, and is
often sold in blister packs or resealable packets. These can
contain a variety of ingredients such as bloodworms, Daphnia,
or brine shrimp, and are commonly used to feed such fish as
Discus which require a high protein diet. Often fed on beef heart
fish food within the aquaculture industry, the discus fish are not
the only fish which can benefit from a high quality prepared
frozen mixture such as beef heart, although by far these are the
fish most associated with this particular frozen food. Live foods
Live fish food is a type of fish food that is fed to fish in its live
form. It triggers instinctual feeding habits of fish. The movement
of live food, such as a wiggling worm, makes it irresistible for
even the pickiest feeders.
While the majority of fish keepers feed exclusively dry aquarium
fish food to their fish, professional breeders often incorporate
live fish food as part of the fishes’ diet.
It is true that aquarium fish food that are manufactured by most
leading brands are formulated to meet all of the basic
nutritional requirements of fish. However, live fish food provides
something that the dry pellet and flake food does not.
Here are some benefits to live fish food, and reasons why they
are necessary:
- Fish that have been introduced from the wild are not
accustomed to eating dry food. These fish will most likely
require live food for a period of time. Some fish may beable to acclimate to dry feed and require live food
indefinitely.
- Newborn fry need to learn to eat dry food. However, when
they see a small organism wiggling in front of them, they
know it’s food by instinct. They chase after it and swallow it
immediately.
- Newborn fry of many fish species are extremely small. Due
to their small size, they are mechanically limited in what
they can eat. When finely crushed flake food is not small
enough, live fish food may be necessary.
- Adult fish that regularly eat dry feed may still need live fish
food to breed. Even if the nutritional content is present in
the pellet feed, sometimes they simply require the live food
to convince them to breed.
- Many live fish food contain a high percentage protein
content, as well as other nutritional components. Due to
the highest nutritional content retained in live foods, it is
beneficial for various fish of different stages.
As a word of caution, live food can be a host to parasites,
diseases, and contaminants. Only live food collected from a
trusted source should be used. It is always better to cultivate
your own live food when possible, since it can be better
managed and controlled. In addition, cultivating your own live
food is often more cost effective in the long term.
Live fish food include earthworms, sludge worms, water fleas,
bloodworms, and feeder fish. Food for larvae and young fish
include infusoria (Protozoa and other microorganisms), newly
hatched brine shrimp and microworms. These are the most preferred type of food for fishes, but are difficult to get. However,
freeze dried forms of earthworms, tubifex etc. are available now.
How can we make our own live fish food,
Mealworms can be kept alive for extended periods in trays filled with scraps and
wheat bran along with a good lid, and glass shrimps can be kept in a well-aerated
tank for several weeks. For smaller fish, daphnia and brineshrimp are ideal for
breeding and raising at home.
Why we should use live fish food,
Prepared foods are definitely more convenient and less expensive. However, Live
Fish Food has several advantages that prepared foods don’t
