The duration between the eggs in the nest and till the time they get hatched is the service done by the male for looking after them. It takes no long time to hatch it out some take very few days to do so. If he sees the eggs falling out of the betta fish bubble nest the male bettas catches it up and drops him back to the nest.

The male bettas watch out for the babies as the predators could try to eat them up ven the female bettas if given a chance could do the same.

It is not necessary that bettas keep on building betta fish bubble nest during their entire time. There are other factors too for this production like the potential for making it, as well as how often to be made. In all cases, breeding season makes it vital for the greater production level. Betta are also skeptical with the presence of female bettas as their presence just not stimulate them but also attracs them clores for great production giving instinct action.

Female bettas just have to swim around the male betta to provoke male bettas to build up Bubble Nest. Water temperature has a significant role to play in this entire scenario. Warmer temperatures increase breeding and create the flurry of things to foam nest resulting bubbles. If bettas get enough space to build the nest they just no waste time and start building the betta fish bubble nest as per desired. For example, you need to maintain the temperature between 78 and 82 degrees for the happy and healthy living of bettas.

By keeping this temperature you build the interest for bettas to breed and build the nest. But there are times when they don’t commence and end up just swimming here and there. Well, it’s not your fault you just need to be patient at times there maturity level matters if they dont want to breed now. Even the time and instinct depends on the bettas as all this work on their desired wish.



If your see the size and everything else, the frequency is USP of this fish. Some bettas will build their bubble nest on a regular basis. Others would come up with a monthly or weekly cycle. While some are lethargic while some grow up through stimulation. It is also possible the one who used to create monthly can turn to weekly and then daily finally not even a single day.

It happens to some of the bettas who show some enthusiasm at beginning but then get deprived later. This is just a common thing you don’t need to get worry about it as there are some bettas who almost never bubble the nest which is no requirement for that betta. Well, you might know why do they build this bubble nest as it is a part of their breeding process. Nevertheless, the male bettas even just for their daily routine also can build this bubble nest if not breeding then as it becomes their natural tendency to do so.

See to it that the betta fish is held up in a proper tank unlike a concave or half Moon tank as their behavior is very anxious and such tanks obscure proper vision for these sweet little betta fishes. This makes them very much annoying and can effect their health directly. Also do not keep them in small tank. Firstly, you won’t find any space for betta fish bubble nest in these little bowls and secondly, irrespective of people what they may say, bettas look out for large environments where they can happily enjoy there freedom and be active. Consider a tank which is of about 2-3 gallons so that they can have enough space for swimming around.

Maintain a clean and tidy tank that doesn’t mean it will be spotless. Always remember, betta fishes love to live in muddy, shallow pools of slow- moving, dirty or stagnant water, being a wild fish. Even in such space they turn out to be so active to find a secure place for their betta fish bubble nest building. Keep this is mind to not disregard your bettas, replace 1/3 new water at one time with fresh water once in a week. It helps to promote betta fish bubble nest building if you maintain your fish tank. If you see an existing betta fish bubble nest, you may scoop it out with care and replace it. No need to get worried about bettas getting anxious as they won’t get angry so soon because of your destruction. They will just make a new one.

Have an eye on your filter. If your filter tank causes too much of a current on the surface specifically then your bettas won’t be able to build betta fish bubble nest. Just like bettas like to move in slow movement similarly it would be good enough to make your Filter work at low level so that there are no chances emerging of current or ruining the mood of your bettas.

Try to control the temperature. Make an arrangement for a heater or heating lamp which fits the size of your fish tank. You certainly don’t want to overheat your bettas and end up causing a harm instead of helping him. Find a source where you can get heat for the small 2-3 gallons of fish tank and try to keep the temperature between 78 and 82 degrees Fahrenheit so that they get prepare for their breeding process.
