Breeding Aquarium Fish: Beginner's Guide to Breeding

Art Aquarium 2015

Everyone who participates in the pastime of keeping aquariums should be able to marvel at the miracle of watching a couple of fish they choose mate, give birth to fry, and then grow the fry to adulthood. In the hobby of keeping aquariums, there is no greater sense of accomplishment. Additionally, it offers you extra fish that you have raised that you may donate to other hobbyists.

Which Time of Year Is the Best Season for Breeding Fish? 

The majority of fish reproduce more actively in the spring when the water is warmer and the days are longer. By doing water changes, raising the temperature setting on the aquarium thermometer, and progressively lengthening the time the lights are on, you may reproduce this at any moment in your home aquarium.

You may train the fish to reproduce by establishing an environment that is as similar to the pair of fish's native habitat as possible and giving both the male and the female an abundance of high-protein food. There are numerous aquarium configurations, plant kinds, breeding surfaces, and diets that are optimal to induce spawning for diverse fish species since different fish species deposit their eggs in different ways.

What Should You Look for When Selecting a Breeding Pair of Tropical Fish?

Choose the pair with the best color, size, and general vitality. The late winter and early spring are the greatest times to discover specimens in your neighborhood aquarium shop that are trained and prepared to procreate. The fish are encouraged to reproduce in the spring on the tropical where they are kept in Florida, or potentially in southern Asia, often in indoor tanks. The juvenile fish are then placed in outdoor ponds to mature until they reach the right size to be shipped to aquarium shops. The ponds contain enough live food for the newborn fish to eat right away, and as they develop, the fish are fed pelleted food. The fry will be fully grown by fall, and if you're lucky, you'll be able to find a nice pair of fish that are ready to mate in your neighborhood fish market!

How Should You Care for the Fish When You Get Home?

Depending on how they deposit their eggs, put the breeding couple in their own tank with the proper spawning substrate or décor. Feed them more frequently than you would regularly feed your neighborhood aquarium fish, usually three times each day, and a lot of high-protein food. You are preparing them for breeding, so their bodies must have enough energy for both their own upkeep and growth as well as for the production of eggs. If at all feasible, feed live brine shrimp to both the male and female. In the absence of such, frozen will work.

For certain animals, keeping the men and females apart—ideally with a glass partition so they can see each other at all times but can't touch—increases the drive to reproduce when the opportunity arises. Increase the temperature to to 78–82 degrees F during this conditioning phase, which is warmer than your community aquarium is typically kept at.

When all of these actions are done at once, the female will become overburdened with roe or eggs. If this is a crucial component for the species' ability to reproduce, it is also crucial to raise the pH, water hardness, and alkalinity to the values recommended for that species' reproduction.

What Is Meant by "pH Value"?

Test kits and strips are commonly available for purchase at aquarium stores, and they may be used to quickly establish the pH value, which is the acidity/base balance of the water. It is common knowledge that most fish species like a somewhat acidic environment in their aquarium water. Some species, like African cichlids, could prefer a basic (higher pH) water, though. For the precise water parameters desired by the kind of fish you are attempting to raise, check aquarium fish websites and fish breeding manuals. By adding pH adjusting chemicals available at your neighborhood fish store, the pH of the water may be changed to suit the requirements of your fish species.

If You Chose Egg Layers That Need Infusoria to Feed the Fry, How Can That Be Produced?

Providing the newly hatched fry with food that is tiny enough for them to ingest so they may live and grow is one of the most difficult aspects of rearing egg-laying fish. The majority of aquarists choose to feed their fry as their first diet. Small aquatic creatures such as bacteria, protozoa, algae, and microscopic crustaceans are referred to as infusoria.

As soon as the adult fish spawn, put a lettuce leaf in the spawning tank to generate infusoria. The leaf will decompose and produce enough infusoria for the first few days. After that, the old leaf can be taken out and a new one added. A week later, you can feed your fish any of the finely powdered prepared foods available in the aquarium store or commercial paste food preparations like Liquifry.

What Are Other Fry Foods That Can Be Used?

Later, the fry may be given the paste made from the yolk of a hardboiled egg and some water, which is added to the tank next to the fry (they may not be able to swim very far yet). As the fry mature, the diet may be supplemented with tubifex worms and fish food that has been mashed between your fingers. Keep in mind that feeding fry is always the most crucial thing to do. This calls for at least six feedings of juvenile fish each day. If not enough food is consumed, fry can soon reach the point of irreparable famine.

If You Only Have Room for One Breeding Tank, What Size Is Best?

The 10-gallon aquarium is plenty for you to breed practically any starter fish species, is affordable, easy to keep, and easy to purchase supplies for. As your interest in the pastime grows, you might need longer tanks for fish whose mating instincts demand them to run quickly or higher tanks for depth. A standard 10-gallon aquarium with with an air pump, sponge filter, powerful heater, and effective lighting will accomplish the task and not cost an arm and a leg.

A has the added benefit of being large enough to house fish, rear their fry, or, after the project is complete, store conveniently in a closet with all of its components neatly packed inside like a box.

So, Where Do You Begin?

Egg scatterers like the zebra danio and rose barb, as well as substrate spawners like convict cichlids and firemouth cichlids, are the easiest egg-laying fish to start with. It is essential to start with the fundamentals until you feel comfortable caring for baby fish because many other species lay their eggs in a variety of methods, including mouthbrooders that carry the eggs and even the young in their mouths.
