Whether you’ve noticed a pump on your betta fish’s belly, or you’re willing to breed betta fish in your tank, you’ll probably wonder, how many babies do betta fish have?
Most betta fish breeds lay around 30 to 40 eggs per spawn, while other breeds can lay up to 300 eggs.
Betta fish, also known as Siamese fighting fish, are such a stunning fish to keep. The stunningly looking fish have a fascinating life cycle.
In this article, we’ll tell you everything you need to know about betta fish babies. How many they have, what to feed them, and how you can take care of them. Stick around!
How Many Babies Do Betta Fish Have?
There are many breeds of the betta fish available. On average, they lay around 30 to 40 eggs each spawning. Yet, this number can vary greatly, as some breeds can lay up to 300 eggs!
Some experienced breeders can manage to provide the best environment for the fish; so, they can lay up to 500 eggs.
Once the female lays the eggs in the tank, the male proceeds to fertilize the eggs in the water. Then the male will move the fertilized eggs into the bubble nest.
It takes around three days for the eggs to hatch. Once they hatch and learn to swim, the parents will stop taking care of the fish and leave them to grow on their own.
So, unfortunately, not all the fry survive. The fry needs special care and suitable environmental conditions to thrive. They might even need a tank of their own to grow in it.
How Many Betta Fish Babies Survive?
Under suitable conditions, around 90% of the fry will survive. If you’re losing more than 10% of the baby fish, that means there’s probably something wrong with your aquarium. You need to figure out the issue to save the rest of the fish.
What Might Lower the Survival Rates of the Fish?
If you’re keeping other fish in the same aquarium, you should keep an eye on any aggressive behavior they show. Betta fry is better grown in a separate tank from your other fish.
It also might be due to some unsuitable conditions in your aquarium tank. For instance:
- High ammonia or nitrate levels
- Unsuitable pH levels
- Not enough food or too much food
- The tank is overcrowded
Taking Care of the Betta Fish Babies
Betta fish are very territorial in general. So, it’s best if you set up a separate tank for them.
After laying the eggs, female betta fish tend to eat some of the eggs they’ve laid. So, it’s a good idea to transport the female fish to another tank after laying the eggs.
The male betta fish will take care of the eggs for the next two to three days until they hatch. It will start forming the bubble nest and moving the fertilized egg into it.
It’s worth mentioning that you shouldn’t disrupt the bubble nest; it may damage the eggs. Additionally, It’s a stressful task for the male fish to repair the damage.
There’s nothing to worry about if you see the male eating a few eggs. They probably weren’t fertilized and will rot inside the tank.
After the eggs start to hatch, the fry won’t be able to swim. The male fish will place them back into the bubble nest until they learn how to swim.
Once they learn how to swim and leave the bubble nest, the male fish’s job will be done, and they’ll be on their own. Now it’s time to transport the male fish back to its tank and start taking care of the fry yourself.
What to Feed the Betta Fish Fry?
In order for betta fry to thrive, they need to be fed living food 3 to 5 times a day. There are various options available for live food. For example:
- Banana Worms
- Baby brine shrimp
- Vinegar Eels
- Grindal Worms
It’s best to start feeding them with minuscule food options like the microworms and the infusoria for their first three days. As they grow, you can feed them larger-sized food like baby brine shrimps.
At the age of three to four weeks, you can introduce worms and daphnia to their feeding schedule. You can also still feed them baby brine shrimps.
Betta fish fry will mature at about two to three months of age. At that age, they can eat dry fish food.
You need to find them homes by then, as they will become territorial and show aggression against each other.
Maintaining the Fry Tank
The baby betta fish are more susceptible to changes in the tank than the mature ones. So, you must keep the tank in its optimal condition for the fish to be safe and thrive.
Aside from keeping ammonia and nitrite at the safe levels, which is 0ppm, the following conditions are best for the fry to grow in:
- The pH level should be between 7 and 7.3
- The temperature of the water should be around 84 and 88 degrees F
- Feeding the fry 3 to 5 times per day, the fry should eat for at least 5 minutes each meal
Many aquarists suggest a daily 5-10% water change. Other aquarists recommend a 25% water change every two weeks. Either way, it’s important to keep the water clean.
To sum up
Betta fish usually lay around 30 to 50 eggs. Some breeds can lay up to 300, and under the care of expert breeders they can lay up to 500 eggs.
Around 90% of the fry will survive. If your fry survival rate is less than that, that means you might have a problem with the conditions in your tank.
It’s best if you grow the fry in a separate tank away from their parents and other fish. The fry needs to be fed 3-5 times per day until they mature.
It’s essential that you find them homes when they mature after 2-3 months. As betta fish are extremely territorial and love to have their own space.
