Paradise fish in a bowl
I wouldn’t recommend putting Paradise fish in a bowl just as much as any other fish. It’s not only harder to maintain it’s also a bad environment for any fish, not just paradise ones.
I can recommend you to build an aquarium with paradise fish this way. Usually, it is in a monoculture in a capacity of two liters per fish, elongated, preferably low or, say, low, with a single species of fish paradise fish. The aquarium is densely planted with plants such as water fern, Vallisneria, Water lettuce, riccia. The area on the water surface that is closer to the light should be free of floating plants, and plants that take root in the soil should not disturb fish in their mating games. Therefore, it is necessary to take out floating plants regularly to avoid their growth over the entire surface.
You should know that adding fresh water to the aquarium has a stressing effect on paradise fish and especially in a bowl, resulting in internal struggles for territorial benefits. Soothing for them is not only the “old” water but also a temperature drop below 20 C. However, it is possible to achieve a favorable coexistence of species at higher temperatures (24 ~ 26°C),
it is necessary to replace every three weeks a quarter of the water. In addition, this should be done at night, when the light is turned off and the fish are calm in the dark and the water has until the morning to stabilize.
Lighting also affects the behavior of fish. You can use it by adjusting the light intensity, but usually, this type of fish likes good lighting.
The water temperature strongly influences the color of the fish-low suppresses the color of the body and mouth-the content of paradise fish at temperatures above 20°C contributes to intense color and color variety.
Food for paradise fish preferably live mosquito larvae or cyclops. To diversify the food, you can also give dry Daphnia. If you have paradise fish in a bowl small water basin will get cloudy easily because of small size. Always makes sure that your fish pets eat everything in a couple of minutes.
In addition to heating (if the fishkeeper keeps fish at elevated temperatures) with a voltage regulator or thermostat, you must provide the aquarium with a mechanical filter. The cover glass should not cover more than three-quarters of the water surface of the aquarium, and it is useful to cover the rest with a net.
Paradise fish (Macropodus opercularis)
The paradise fish is native to China. However, it also appeared in other places. From China, the paradise fish was moved to the reservoirs of Southeast Asia, Africa, Indonesia, Korea, and South Vietnam. In Russia, the macropod appeared in 1904.
A special feature of the representatives of the series is an additional respiratory organ-a labyrinth that occurred under the conditions of fish life in oxygen-depleted reservoirs and can live without oxygen Even though it can live with low oxygen I wouldn’t recommend to have Paradise fish in a bowl.
The rice fields of the native countries of the species are conditions under which polluted irrigation systems, which occasionally become flat, force the animals to adapt in order to survive. In addition, in small puddles, the abundance of different plants contributes to the fact that this species spawns eggs and builds a nest near the water surface, where there is more oxygen and there is a chance that the offspring will not die. In addition to the air coming through the gills, it enters the area of the gill arches, already from adolescence enters air that the fish catches from the surface of the water through the mouth. Though the labyrinth covered with a mucous membrane organ is permeated by many blood vessels saturated with oxygen. Fish breathe and catch air from the surface even in crystal clear and oxygen-rich water.
Due to the adaptability of the paradise fish to live even in spoiled water, it is extremely undemanding for water quality, but like all labyrinth, it takes less than eight hours in a closed container to fish to die so better to not place paradise fish in a bowl. This simplicity applies only to paradise fish, all other labyrinthine ones do not have such features, they prefer clean water that meets certain conditions in the composition. Due to its peculiarity, this fish without water can survive more than a day in the air in the shade or thick wet grass.
Nevertheless, the change of species that have been kept in aquariums for generations has made the fish less robust. This was due to the protection of fishkeepers of paradise fish from sudden changes in nature, which cannot be said about other, more sensitive fish species. It can be due to this long stay of fish in water with a low temperature (below 16°C) causes various diseases and does not contribute to good development.
The low temperature suppresses the main features of paradise fish: aggressiveness for each species, low color, and the ability to mate – the choice of a female, stimulation of maturation before spawning, building a nest, and nurturing offspring and all of it damages the possibility of normal existence of paradise fish in a bowl. The main features of the appearance of species and behavior roots: the extraordinary ability of macropods to recognize other fish by their movements and postures (and even their sounds), about the appearance of food somewhere nearby or even in other aquariums.
According to many fish farmers, the optimal temperature of the macropod content is 20-22°C. under such conditions, the color of the fish is particularly attractive and bright. The fish gets more expressive lines of a strongly compressed body and fins. On a brown-green background, there are wide transverse stripes of red and green, the fins are long, especially the dorsal and caudal fins. In the male, they are longer than in the female. Females are fuller, shorter, and duller and lack the filamentous extensions on the fins that the male has. The body length of the male is 10 cm.
For the breeding of paradise fish, a young male is selected for the female, as the older male is usually persistent and extremely demanding (or aggressive) during the spawning process and can kill the female so better have a more spacious fish tank and not have paradise fish in a bowl.
Manufacturers prepare capacity 6-10 liters, equipped with a heater with the thermostat or turn it over autotransformer (can be without it, if the room in which spawner, the temperature is kept in the range required for spawning), put plants on one side of the spawner so that the female could hide in them, escaping from the pursuit of the male. Part of the water surface should be free of floating plants – riccia, Java Moss. Plants that take root in the soil should not occupy this part of the free water surface with their leaves either.
Two to three weeks before spawning, the Breeders are transplanted into separate containers and fed with the live food. A few days before the producers land in the spawning area, the containers are brought together so that the fish can see each other. At this time, the female” matures ” and the appearance and behavior of the male affect her. The female increases the maturation of eggs at the sight of poses that the male shows. In the same direction also work the sounds of the male, which the female, according to researchers, hears from a distance.
In the prepared containers, the water is taken from an old tank – what it was before the landing of the producers, in the spawning ground it should be re-prepared, but the composition corresponds to the old. You can’t use old water from a functioning aquarium -paradise fish pair are negatively affected by the smells of other fish that used to be in the water.
From this point on, the male begins to take an interest in the female, pursuing her and at the same time building a nest – take air from the surface, mix it with saliva and release it in the form of small bubbles somewhere near floating plants or in the corner of the spawning ground. The thickness of the nest reaches about a centimeter. The building is often interrupted by the male chasing the female – he chases her around the aquarium, Makes threatening noises, and hits the female in the abdomen, which contributes to the rapid maturation of the eggs so you need no to keep paradise fish in a bowl so your fish have places to hide. However, the female should be able to hide from the male in order to rest in the thickets of the plants.
The mature female takes a head position, which means that she is submissive to the male, and then the male invites her under the nest where the spawning takes place. Embracing the female with his body, the male presses her eggs, which are lighter than water and rises in the thickness of the bubbles, into the nest. Eggs that fall to the ground or hang in layers of water are picked up by the male and laid in the nest. During the release of caviar, the male washes it with milk.
Spawning takes several hours. The female lays a thousand eggs with a diameter of more than 0.5 mm.
After spawning, the male drives the female away from the nest. It should be removed, as the male continues to take care of the offspring.
As a rule, the male does not show any aggressive actions against caviar, but the first signs of producers due to their inexperience sometimes eat part or all of the caviar and that chances are increased if you have paradise fish in a bowl. In the case of subsequent spawning with the same producers, this case is not repeated.
The male is deposited out during or after the hatching of the larvae. The stay of a male in a spawning ground with the Fry is undesirable – it can destroy them as well as any living food. For a safe courtship of the male for eggs and larvae, it is necessary to reduce the lighting at night, making it gloomy. In this case, the attitude of the man to the eggs is different and contributes to its preservation. During the spawning season, the producers are not fed.
The larvae hatch one or two days after the marking. In jerks they are attached to all objects: they hang on the walls of the spawning ground, on plants in the upper water layers. First, they settle down and wait for their hour to become fry.
New fry is fed “living dust”. It is desirable to keep this food in sufficient quantity in the spawning ground. After 12-15 days, the fry can feed on an adult Cyclops.
The most important time in the development of fry is up to a month and a half of age when they begin to form a labyrinth. By this time, the aquarium must be well filtered and ventilated for fry and it will be a lot harder to have paradise fish fry in a bowl, and a tenth of the water must be changed once a week.
Fish reach sexual maturity in the sixth month of life.
