Reproduction is different depending on the species but generally happens one of three ways. Eggs are immediately fertilized by sperm from the male when the female drops them in the water. It is possible to have fertilization within the females body before she drops them. The third method is when a female lays eggs and the eggs hatch into tadpoles. This is the most common method of reproduction for many species of fish.

Can different species of fish live together?
Fish That Live Well Together Many species of freshwater tropical fish can work well together in the same tank. Some fish species are better adapted to live together than others.
For example, the bluegill is a good choice for a tank with a lot of other fish, but it is not as good at living in a community tank as the yellowtail, which is better suited to a smaller tank than a larger one. In general, however, there are some fish that are best suited for living together, and these are listed below.
Bluegills (Lampropeltis lanceolatus) – These are the most common freshwater fish in aquaria. They can be found in almost any freshwater habitat, including lakes, rivers, streams, ponds, creeks, swamps, marshes, estuaries, lakeshores, coastal areas, etc., and are generally considered to be the best of the freshwater species.
Their large size makes them easy to handle and they are often used in aquariums as food fish or as part of a group of fish. Many aquarists also use them as a food source for small fish and invertebrates.
Can two different types of fish have babies?
Female fish can breed a new species if they aren’t choosy about who is Mr. Right. According to a study published in the Journal of Fish Biology, fish will mate with a species outside their own if the male’s coloring is attractive enough or if the female can’t see him properly.
What fish can crossbreed with guppies?
Endler guppies and mollies are some of the most common fish species in most fish shops. Most of the time the fry of endler guppies and mollies will not survive in the wild. Fancy Guppy (Poecilia reticulata) The Fancy guppy is a very popular fish for aquarists, as it is very easy to care for, and can be kept in almost any aquarium.
It is also a good choice for beginners because of its ease of care and the fact that it does not require a lot of fish food. The Fancy is one of those fish that you will want to keep as long as you can, because it can live for many years in captivity. In fact, it has been known to live up to 100 years!
Fancy Guppys are known for their large size, but they are not as large as some other fish, so they do not need as much space as other larger fish. They can also live in smaller aquariums, although they will require more space than some of their larger cousins.
What fish Cannot live together?
Cichlids, certain species of sharks, loaches, knife fish, mormyrids and other territorial fish do not share space well with members of their own kind or those of other species. In the case of the loach, for example, it is not uncommon for two or more individuals to occupy the same space at one time.
This is especially true when there is a large number of individuals in the group, such as in a group of fish that have been kept together for many years. In this case, the individual that occupies the most space is the one that is most likely to be eaten by other fish.
The same is true for the knife-fish, which is often found in groups of more than two individuals. It is important to remember that the size of an individual does not necessarily determine its ability to defend itself against other individuals of its own species, and that a larger individual may be more aggressive than a smaller one.
Can guppies and goldfish live together?
What is this? It is possible to keep guppies and goldfish in the same tank water. The temperature needs to be around 72-74F, which is on the high side for goldfish and on the cooler side for guppies. It’s not the only consideration when deciding whether fish should be kept together, but it is a good starting point. If you have a guppy tank, you may want to consider keeping it in a separate tank from your fish.
This will allow you to monitor the fish’s health and keep them separate from the rest of the tank. If you do this, make sure that the water temperature is not too hot or too cold, and that there is plenty of hiding places for them to hide in. You can also use an aquarium heater to help keep the temperature at a comfortable level.
Can koi and goldfish crossbreed?
Like many interspecies hybrid, the goldfish and koi are sterile. Even with other hybrid, they cannot reproduce. If the hybrid is male or female, it doesn’t matter. There are no exceptions to the rule that both sexes will be sterile.
Koi are the only species of fish in the world that do not produce eggs. They do, however, produce sperm, which can be used to fertilize an egg. The fertilized egg then develops into a new fish, and the cycle begins again.
