FACTORS AFFECTING FISH DURING BREEDING PERIOD
During the breeding period, protein-rich foods are essential and are the main source of nutrition for fish.
The water temperature in the pond also affects the gestation period of fish.
For example, at 25°C, the gestation period of Guppy is 28 days, but if the temperature increases to 32°C, the period will decrease to 19 days. This will be dangerous because the baby fish will die soon after birth or their lifespan will be shortened.
NEWLY HATCHED FISH
After hatching, the fry are provided with food through a small yolk sac that remains hanging under the fish's belly. When this sac disappears, the fish must find food for themselves. Normally, newly hatched fry look like their parents. However, in some species, such as discus fish, newly hatched fry are completely different from their parents, and only when they grow up do they resemble their parents.
BABY FISH TANK
Most aquarium keepers set aside a separate tank to raise their newly hatched fry. After the parent fish have finished their feeding period, they are removed so that the fry can feed independently. During this time, the water filtration system will be temporarily turned off to prevent the fry from being sucked up, leaving only the aerator to provide oxygen to the fry. If the weather suddenly changes, a water heater should be used to regulate the water temperature. When using this type of device, you must ensure that it is covered with an insulating layer to avoid scalding the fry.
FEEDING THE FRYS - BABY FISH
During this period, it is necessary to apply a feeding regimen for the fry because this is the time to decide whether the fry will continue to grow or die. Therefore, each day the fish must be fed 3-4 times. Each time you feed the fish, remember to spread the food evenly throughout the tank because the fry at this time rarely move but just lie in one place. If you do not do this, the fish will not eat enough and grow slowly.
THE DANGER OF HAVING TOO MANY FRY - BABY FISH IN A TANK
A large number of baby fish is a concern when taking care of. At this time, it takes a lot of time to change the water every day because too many fish will make the water dirty and polluted quickly due to fish waste and leftover food at the bottom of the pond. At this time, you have to consider which type of filter is most suitable for the baby fish because they can be sucked up when swimming near the pump. If possible, you should divide the baby fish in half and raise them in 2 separate ponds. This way, the fish will have enough space to live and grow, avoiding infectious diseases due to dirty water, stunted bodies due to fighting for food in the school...
PROBLEMS AND SOLUTIONS
It starts with the fish not being able to reproduce. This may be because the fish cannot find a suitable mate or the fish is too young to reproduce. If the fish has laid eggs but they do not hatch, it may be because the male fish is too old and has weak sperm that cannot fertilize or the male fish has damage to its genitals.
In addition, the cause may be due to the eggs being attacked by fungus, then you must use Methylene Blue solution to kill the fungus and restore the water temperature to normal because when fungus appears, it is a sign that the water temperature is too low.
If the baby fish do not develop or die, check the diet to see if there is anything wrong with the fish. Use a magnifying glass to look at the belly of the baby fish, if there is no food, it is probably because the fish died of hunger.
It could also be that the water is too dirty, causing the fish to get sick and die. In that case, you should check the filter to see if it is too dirty and clean it. If the fish density in the pond is too high, you should change 50% of the water every day to limit fish diseases.
