Investigating the Myth of Female Bettas Laying Eggs Without a Male

The myth of female bettas laying eggs without a male betta has been circulating for years. The idea that a female betta can reproduce asexually has been the source of much speculation and debate among fish enthusiasts and experts alike. But is it true? Can female betta fish lay eggs on their own and reproduce without a male partner? In this article, we will investigate the myth of female bettas laying eggs without a male and explore the science behind it. We’ll take a look at the biology of bettas and the conditions necessary for them to reproduce, and consider the evidence for and against the myth. By the end, you should have a better understanding of the truth behind this age-old myth.

Biology of bettas

Female bettas are members of the species called “platyfish,” and male bettas are members of the species called “mullet.” The platy fish species include the X-ray tetra, the goldfish, and the zebrafish, among others. Bettas are a member of the mullet species, which also includes the silverfish and the whirling dervishes. Although these species look very different, they all have a few things in common.

They all possess gills and fins, which are used to swim and move oxygen through the body. They have scales instead of feathers or fur, so they can breathe underwater. They all have a Y-shaped chromosome structure. And they all have a reproductive system that includes external fertilization, meaning the female and male exchange sperm and eggs in the open water instead of internally.

Conditions needed for bettas to reproduce

Before discussing the evidence for and against the myth, it’s important to understand the conditions that are needed for bettas to reproduce. For female bettas to lay eggs, they need warm water, a longer day length, a nest, and a male partner. They also need a breeding trap, which is a type of aquarium that’s designed to keep the female betta until she lays her eggs. Warm water: Female bettas need warm water to lay eggs.

Lower temperatures can cause the eggs to die before hatching. So water temperature is one of the most important factors when breeding bettas. Longer day length: The day length must be long before female bettas can reproduce. The exact length varies depending on the species of betta, but it’s typically between 13 and 14 hours. Nest: Bettas need a warm and quiet spot to lay their eggs.

A glass jar works well because it keeps the eggs warm and limits movement, so they don’t get sucked into the filter. Male partner: A female betta can’t reproduce on her own because, unlike other types of fish, she doesn’t have the equipment to do it. Female bettas don’t have a gonopodium, which is an organ found in other types of fish that transfers sperm to the female during mating.

Evidence for the myth

There have been several claims over the years that female bettas can lay eggs without a male partner. Many of these claims come from people who have found what appear to be unfertilized eggs in the tank of an otherwise healthy female betta. However, these claims are not always correct. Unfertilized eggs can be confused with unfertilized eggs in these situations.

Eggs that don’t get fertilized become “slime eggs” that are generally unswimmable and appear to be unhatched. So if a betta owner finds what looks like slime eggs in the tank, they may conclude that the eggs are unfertilized. But they may be mistaking eggs that have been fertilized but haven’t been properly incubated for slime eggs.

To have evidence that the eggs have been fertilized, the owner would have to know what the eggs would look like if they were fertilized. They would also have to have evidence that the female betta is healthy. So in many cases, there is no real evidence for the myth.

Evidence against the myth

On the other hand, there is also a lot of evidence against the myth that female bettas can lay eggs without a male partner. First, there is no species-specific evidence for the myth. It simply isn’t true for any female bettas anywhere in the world. Male bettas are necessary for reproduction, and they’re responsible for getting the process started.

They do this by producing mucus that contains sperm. They then swim toward a female betta and use their fins to hold her in place while they shoot the mucus toward her. The mucus either lands on her body or gets caught in her fins. From there, the sperm swims to the female’s eggs, where they fertilize them and start the hatching process.


The myth of female bettas laying eggs without a male appears to have arisen from misunderstanding the biology of these fish. For female bettas to reproduce, they need warm water, a longer day length, a nest, and a male partner. Bettas are a type of fish called an external fertilizer, which means that male bettas must shoot their sperm toward female bettas to fertilize their eggs. So female bettas can’t reproduce on their own.
