Other fish are only able to reproduce during a particular season of the year when the water temperature is right or when there is ample food available to bring the fish into breeding condition. Some fish only reproduce once and die shortly after they have spawned, for example, the Pacific salmon.
Most wild species mate in spring when the water becomes warmer and the daylight hours are longer. So, you can stimulate your fish to spawn by replicating those conditions in your home aquarium. Begin by carrying out frequent water changes, raising the tank temperature slightly, and slowly extending the length of time that the lights are on.
Carry out research so that you know what kind of planting, breeding surfaces, and substrate are preferred by your fish, and try to copy that in your breeding tank. When choosing a pair of fish that you intend to breed from, be sure to choose the pair that has the brightest color and appears lively and in good overall condition.
Most fish are able to breed once they grow large enough and reach maturity. So, pick a pair of fish that are of a reasonable size. Remember that in many species, female fish are smaller and less brightly-colored than males. The fry is placed into outdoor ponds until they grow large enough to be shipped to fish stores. These youngsters have been conditioned by being fed a good diet, including live foods and pellets. By the fall, the fry is mature and ready to breed, and you may find a perfect pair in your local fish store.
Whether you choose egg layers or livebearers, you will need to feed the fry, and that can be the trickiest part of breeding fish. The fry of egg layers feeds on the egg yolk sac for a few days after they hatch. After that, you will need to feed them. Most fish breeders use infusoria as a first food for their fry. Infusoria are tiny micro-organisms that live in the water, including crustaceans, algae, bacteria, and protozoa.
You can grow infusoria, simply by putting a lettuce leaf in the breeding tank, as soon as the male and female fish start spawning. At that time, you can remove the old lettuce leaf and replace it with a fresh one.
After another week, you can begin to feed the fry with one of the finely powdered fry foods for sale in your local fish store. Commercial paste preparations are also available, including Liquifry. There are many variations of breeding in fishes. If you want to try breeding fish, there are plenty of aquarium species that are pretty straightforward to breed. We suggest that you begin with livebearers, such as guppies that seem to spend much of their time reproducing!
As you become more experienced, you may want to try rearing other, more challenging species. Bearers : These fish carry their young as they develop, either inside the female or outside, often in the mouth of the male. Sharks, rays, molly and gambusia give birth to live young.
Fish School. How Do Fish? Wild Things. Texas Dinosaurs! The Pacific Salmon. They are, in general, easier to breed than egg-layers. Once you have some experience with live bearing fish, you can move on to more hardy egg-laying fish such as Barbs and Danios. The advantages of breeding livebearers rather than egg-layers are that the parents mate easily without much help and once their fry are born, they are much less needy. When you choose your fish, you need to make sure that you have at least one male and one female the ratios vary depending on the species.
Other than ensuring you select the right sex, you need to make sure the parent fish have good colorings and markings and that they are healthy and mature.
It is also vital that they are compatible. If some species are just thrown together, one may bully the other to death. Once you have chosen a suitable pair or group if they are shoaling fish they should be conditioned.
Conditioning means to feed the fish a variety of foods to ensure they are in the best shape possible before they breed. Some species require bare tanks or a separate tank for breeding and raising the fry, other species require certain plants, water flow.
Bring the water pH and hardness to the required levels specific to each species and also raise the tank water temperature by about 10F above its usual temperature. By separating the male and female fish with a glass partition, this also increases the desire to breed when they are given the chance.
The water in your tank should be heated up to around 82 o F 28 o C. You should ensure the rest of your water parameters are reading correctly before you attempt to breed.
Place a removable divider in the center to separate the male and female before you introduce them together. A sign that they are ready to start mating is when they begin to establish bubble nests.
Females develop upright bar markings on the side of their bodies which indicate they have reached sexual maturity too. Remove the divider once the male Betta has built a bubble nest this can take anywhere from a few hours to a few days.
When they are first placed together, you may notice them fighting. This is normal, and part of the mating ritual but keep an eye on them to make sure neither is injured. If a male is interested in the female he will flare out his gills, spread his fins and twist his body.
If a female is interested she will curve her body back and forth and turn a darker color. The male will circle her and take his time in deciding the best positioning. They will then embrace known as the nuptial embrace for a few seconds, and the female will release eggs. Each time they embrace the female will release between 10 and 40 eggs. The embracing will continue until the female has no eggs left.
The female should be removed from the tank as soon as she has released all her eggs — she will usually eat the eggs. Once she has been removed, the male will fertilize the eggs by released milt into the tank.
