Beta Fish Bubble Nest
Ever wonder where that group of bubbles floating at the top of your beta fish tank came from?
Often appearing overnight, these bubbles were made by your male beta fish.
The bubble nest is build by a male beta fish as he prepares for mating. The bubble nest serves two main purposes. The first is to attract a female; the second is to store the fertilized eggs before they hatch.
Often the male beta fish will build the bubble nest overnight while in the dark although sometimes you may get lucky enough to see the male in the process of building the nest.
The male beta fish will go to the surface of the tank and take in a little air. He will then swim below the surface and release the air forming a bubble. The beta fish also releases some mucus along with the air, helping to form the bubble and further ensuring the safety of the beta fish eggs.
Males are very particular over their bubble nest and will often maintain it everyday.
If you notice your male beta fish building a bubble nest and you don't plan to bread the beta there is no reason for concern.
A bubble nest is a natural process in the male's development and maturity. It is also a sign that your male beta fish is healthy and happy.
However if you're beta does not build a bubble nest it doesn't necessarily mean he is sick.
