Do fish breed naturally?
Some species of fish reproduce by themselves. These fish are females, and so are the young they give birth to. It’s debatable whether this can actually be called ‘mating’ but it is certainly a way to reproduce. The females may mate with males, but the sperm is not used for reproduction.
How do fish breed?
Fish reproduce by bearing live young or by laying eggs. Livebearers give birth to fully formed and functional young called fry. The eggs are fertilized and hatch within the female.
What do fish look like when mating?
Your fish will show signs of mating before the actual mating happens. Look for fish that pair off or groups of males showing interest in a female. In other species like the parrot and oscar fish, males will rub against the females and wiggle or vibrate their bodies. In some cases they will lock lips as well.
Where do fish lay their eggs?
The methods of reproduction in fishes are varied, but most fishes lay a large number of small eggs, fertilized and scattered outside of the body. The eggs of pelagic fishes usually remain suspended in the open water. Many shore and freshwater fishes lay eggs on the bottom or among plants. Some have adhesive eggs.
What do fish do when mating?
In this type of mating, the female is impregnated by one of the male’s dorsal fins. Sperm is released from the fin and this enters the female fish’s body. Within one month, the female will release a hatched fish, that’s also called as larval fish or fry.
How long is a fish pregnant?
As examples, the female swordtail and guppy will both give birth to anywhere from 20 to 100 live young after a gestation period of four to six weeks, and mollies will produce a brood of 20 to 60 live young after a gestation of six to 10 weeks.

Does fish produce sperm?
Most male fish have two testes of similar size. However, most fish do not possess seminiferous tubules. Instead, the sperm are produced in spherical structures called sperm ampullae. These are seasonal structures, releasing their contents during the breeding season, and then being reabsorbed by the body.
How do I know if my fish are happy?
Your fish are happy and healthy when they:
- Swim actively throughout the entire tank, not just hanging out or laying at the bottom, floating near the top or hiding behind plants and ornaments.
- Eat regularly and swim to the surface quickly at feeding time.
Why are my fish chasing each other?
Fish chase each other for a variety of reasons, such as defending their territory, establishing dominance, competing for food, and mating. Even fish that are typically docile fish may chase others because of constant stress. This could be due to incompatible tank mates, poor water conditions, or an overcrowded tank.
Do female fish have periods?
Fish do not have periods. They have internal sexual organs and ovaries that produce unfertilized eggs once a year. When the eggs have matured, the female will eject them into the water for external fertilization by the male. This process, called spawning, makes a menstrual cycle in fish unnecessary.
How do mermaids have babies?
The female will lay the eggs and they will be dispersed through the water where the male will fertilize them. But some fish engage in a form of intercourse or a mating ritual. There are also types of fish that can fertilize themselves. The best hypothesis for mermaid reproduction is that they mate in the same fashion.
What do I do if my fish has babies?
After Your Fish Gives Birth
- For many species, it’s important to keep fertilized eggs and newly hatched fish, or fry, separate from the adults.
- When moving the fry to a separate tank, use the water from the original tank.
- Some adult fish are caretakers.
- Create a good home for the fry.
