What tropical fish are oviparous, and whether tropical fish are eggs or fish

Nonsense! Fish are all viviparous.

1. It depends on the species of tropical fish.

2. For example, guppies.

Small fish such as Red Arrow and Black Mary are produced directly. And the aquarium fish of the short snapper class.

It is basically spawning, and maps, colorful colors, etc. are also spawning.

3. Therefore, it cannot be generalized, and it is necessary to look at the species of tropical fish to know whether it is spawning or directly giving birth to small fish.

Most tropical fish spawn, and there are more small oviparous fish. There are some special tropical fish that are viviparous, such as sharks. In addition, there is a special mode of reproduction, which is ovoviviparous.

For example, a small number of tropical fish are ovoviviparous, although the eggs are fertilized and hatched in the mother's body, but the small fish do not absorb the nutrients of the mother in the mother's body, but the eggs absorb the nutrients in the mother's oviduct.

Therefore, tropical fish generally lay eggs, but different species of tropical fish have different ways of reproduction.

What tropical fish oviparous

Tropical fish is a very popular aquarium fish. They live in warm waters, and their bright colors and graceful posture are intoxicating. There are many ways to reproduce tropical fish, among which oviparity is a relatively common way.

The following will explore what tropical fish eggs are born from several aspects.

1. The process of oviparity

Tropical oviparous fish refers to the hatching of small fish in the external environment after the mother lays eggs. First, the female tropical fish will choose a suitable place to spawn, usually on aquatic weeds or other objects. Next, the male with a strong appetite eats a large amount of food and then chases the female excitedly.

After mating, females lay hundreds to thousands of eggs. Most of the eggs are attached to objects, and hatched small fish are usually born within three days to a week.

2. Oviparous species

There are two main types of oviparity in tropical fish: mouth hatching and sperm drop. Mouth hatching is when the mother hatches eggs in her mouth, which is a relatively rare type of reproduction.

Sperm eggs are eggs that the mother adheres to the surface of the object and hatches the eggs with the temperature and oxygen of the environment. This method is common and suitable for hatching large numbers of small fish, but can sometimes be threatened by the spinal rolls of other animals.

3. Oviparous characteristics

Oviparity is a common way for tropical fish to reproduce. This method has the following characteristics: first, female tropical fish can lay a large number of eggs in a short period of time, which is suitable for mass reproduction; Secondly, the hatched small fish are small in size and sometimes require special feeding; Again, eggs are easily eaten by other animals and need to be protected; Finally, small fish that hatch from oviparous are more fragile and need to pay attention to the adaptability of water quality and environment.

4. Advantages of oviparity

Oviparity is a common way for tropical fish to reproduce, which has the following advantages: first, it reproduces quickly, lays more eggs at one time, and can make more small fish; Secondly, it is rich in nutrients, and the hatched small fish are small in size, but rich in nutrients, especially suitable for newborn children and other small ornamental fish; Finally, new varieties can be cultivated and stable strains can be bred to meet the needs of people with different tastes.

What tropical fish are ovoviviparous

There are two modes of reproduction in tropical fish, which are oviparous and viviparous. Oviparity refers to the reproduction of offspring by spawning, while viviparity is that the mother fish will give birth to small fish calves directly, and this reproductive method is divided into two types, one is ovoviviparity and viviparity. And today we are going to introduce the ovoviviparous tropical fish.

1. Which tropical fish are ovoviviparous

Many people think that only ventral pore flukes are ovoviviparous, but in fact, this is only a part, and there are many more tropical fish that are truly ovoviviparous, such as some species of mosquito-eating fish, tall multi-scale fish, prongfin moth, swallowtail catfish, giant thorny green acanthus, and so on.

2. Characteristics of ovoviviparity

Ovoviviparous tropical fish have a number of unique characteristics as compared to oviparous tropical fish. First of all, they have a high fertility rate and hatching rate. Since it is in-house, the mother can directly store the eggs and small fish, so as to avoid the possibility of being swallowed by predators during the incubation process outside.

Secondly, ovoviviparous tropical fish need nutrients from their mothers during their growth, which makes the small fish have a higher ability to survive and grow faster when they are born. Moreover, due to the escort of the mother fish during the growth process, the mortality caused by environmental changes can be reduced.

3. How to breed ovoviviparous tropical fish

For hobbyists, wanting to engage in the cultivation and reproduction of ovoviviparous tropical fish requires some special equipment and methods. First of all, you need to have a separate water tank, as well as a filter and heater inside the aquarium. In addition, monitoring water quality is also a very critical step, and it is necessary to ensure that there are few impurities in the water, and that the indices of ammonia nitrogen and nitrate are kept within the normal range.

In the process of rearing ovoviviparous tropical fish, it needs to be carried out in a confined environment to simulate the natural life cycle of fish. It is important to note that when choosing a species, it is important to choose a variety that will adapt well in a home aquarium.

4. Weigh your choices

Finally, when it comes to choosing ovoviviparous tropical fish, we need to weigh the pros and cons. Although ovoviviparous tropical fish have many unique characteristics, at the same time, their survival rate is not necessarily higher than that of oviparous tropical fish, and some species have more stringent water quality and temperature requirements, which can cause some difficulties for those who are inexperienced. Therefore, when choosing, you should choose the right variety according to your actual situation and experience.
