There are several reasons for betta eggs sticking out. So, let’s see them one by one. 

Betta fish female and the male ratio is off

Firstly, if your tank does not have a proper female and male ratio, it can be caused the egg to stick out. Most aquarists, who have only female betta fish in their tank, are experiencing this situation. Hence, some female betta fish do not tend to release their eggs without male bettas in their tank. 

Poor water quality 

Secondly, betta eggs sticking out can happen due to poor water conditions. So, it would be best if you always tried to maintain the water quality at the preferable level. Also, you should check out the ammonia, nitrate, and nitrite levels of the tank water. Then, you should keep them at the minimum level or zero level. Because these substances are harmful to all fish varieties. 


When your fish tank is overcrowded, sometimes fish tends to stick out their eggs. Especially when you rear betta or fight fish, you should highly consider the tankmates. Because They show aggressive behavior towards tankmates. 

Lack of nutrients 

Another factor that causes sticking eggs is a lack of nutrients. Generally, when spawning, female betta needs extra energy. Thus, if you do not provide enough foods or nutrients, they do not have better health to breed successfully.

Because betta eggs sticking out can happen due to poor water quality. However, if your water condition is not better, you should perform a water change as soon as possible.  

Secondly, you can go to Epsom salt treatment. Because if they have any constipation, Epsom salt can fix it. Moreover, you can feed them daphnia. Hence, daphnia is a great food that helps to clean out female fish eggs. Further, daphnia can relax the muscles of female betta fish. As a result of the daphnia diet, females release their eggs naturally. Further, if your betta tank does not have a male betta, you can try this method. You can separate the betta female into a separate tank and introduce a male betta fish to that tank.

At this time, there is a possibility to release the eggs by female betta. In this method, you do not have sure the behavior of female betta or male betta. Also, you have an alternative way to accomplish this. You can put a male fish into the cup and put the cup at the top of the aquarium. But do not put it in the aquarium. Through this, you can leave them for about 2-3 hours alone without a worry.

Also, you can follow this method if you have enough space in your aquarium. If these above methods do not work, you can try fasting your female betta. Avoid providing the food for 3 to 4 days. It is hard, but you should have to do it. Because it leads your female betta to absorb the eggs. In addition to these, you should try to keep your bettas, including female betta fish, without any stress. 

Do female bettas get egg-bound?

Yes. Female betta fish can get egg-bound. Generally, in suitable conditions, female betta fish release eggs into the water. At the same time, male betta release their sperms and fertilize them. This process does not happen if there is no male in the tank or if the condition is unsuitable. However, this time female bettas will reabsorb the matured eggs and wait until next year. But sometimes, female betta fish do not release eggs. Most of the time old female betta fish is facing this unfortunate circumstance.
