What do Betta Eggs Look Like?

So how can one spot Betta eggs in the tank? The answer is simple, by looking carefully. Betta eggs are about 1mm in diameter and are basically white-colored balls, the balls are not perfectly round rather they are oval in shape.

How Many Eggs Does Betta Lay?

Generally, Betta lay about 30 to 100 eggs, this number can even go up to 400! Those surely are a lot of babies to take care of.

The numbers are different for mouthbrooding type Betta. The number of eggs that these types of Betta lay lies between 10 to 20. This number seems quite manageable in front of 100 to 400 which was in the previous case. So it seems more reasonable to keep mouthbrooding types of betta in your fish tank so that the tank does not overflow with betta babies and eggs. But these types of eggs take a very long time to hatch which itself is something most owners do not like.

How Frequently do Betta Lay Eggs?

Bettas are very productive in nature which means that they are quick in reproducing. They can lay eggs after every few weeks. The productivity of a female also depends on its age and size, reproducing might be stressful for betta of around 2 to 3 months of age. A stressed and tired female takes longer to reproduce. Inexperienced male betta has difficulty fertilizing the eggs.

Is the egg fertile?

Not all eggs lead to betta babies. Some of the eggs are useless or infertile. It is very rare that all of the eggs in a spawn are fertile. You can spot a growing or fertile egg by looking at it closely. A fertile egg grows steadily and starts developing gray spots on itself. When the egg is about to hatch, a small fry can also be seen inside. The male betta is responsible for taking care of the eggs and they eat any infertile eggs present.

What does the Hatching Depend on?

There are different factors on which the hatching time of the eggs depends. We will now discuss some of these factors.

Good Water Quality

Water quality has a great effect on the eggs. Poor water quality has a negative effect on betta eggs. If the water has toxins or other chemicals like ammonia or nitrites, the eggs could be killed. So make sure that the water is clean and all the parameters like pH and ammonia levels are in check.

What Does The Hatching Depend On


The temperature has a direct effect on the hatch rate. So at higher temperatures, betta eggs hatch faster. 79 to 82 degrees Fahrenheit is a suitable temperature for betta eggs. But these higher temperatures are not suitable for adult betta so this must be kept in mind.

Type of Betta

As discussed above the mouthbrooding betta eggs take a month to hatch while the bubble-nested betta eggs take only 2 to 3 days to hatch. So the hatching period is obviously different for different species of Betta.
