Male bettas always keep a bubble nest in the off chance that a receptive female happens to swim by.
A

Answer 2

The bubble foam is created by the Male in which the female lays eggs its a sort of a nest. Bubble nests created by male Betta are made from air bubbles coated with saliva to increase durability.

After spawning, the eggs float up into the bubble nest, or are carried there held in the mouth by the male, as if he is eating them. The male lodges them in the nest to protect them, and then protects the brood by chasing away the female and any other intruders, concentrating on the eggs in the nest, retrieving any eggs or fry that fall from the nest and keeping the nest in repair. The father will guard the eggs constantly until the fry hatch in 24-48 hours and be suspended from the nest. For the next few weeks, they will stay nearby being tended by the father.

Triggers of Bubble nest Construction
Bubble nests are built even when not in presence of female or fry (though often a female swimming past will trigger the frantic construction of the nest). Males will build bubble nests of various sizes and thicknesses, depending on the male's territory and personality. Some males build constantly, some occasionally, some when introduced to a female and some do not even begin until after spawning. Some nests will be large, some small, some thick.

Unfortunately the male harasses the female so much to lay the eggs or guard the nest by driving the female that it does more harm then good.

There would nicely be chlorine contained in the water once you replaced it. also, what did you clean the aquarium tank with? in case you only agitated the sand, then sucked the waste out through the tube and replenished 0.5 the water, then further water conditioner you'll nicely be perfect. I have a tendency to shop a bucket of water it really is left status overnite so a number of the chlorine evaporates. also, if the water used to fill up the acquarium has been status at room temperature, then a lot less danger of temperature fluctuation once you upload again to the tank. by no skill empty/clean out the water thoroughly. I used to purpose this when I did no longer have a lot experience at the same time as i turned right into a baby, yet i did not lose any fish from that. This changed into in Asia at the same time as the water temperatures do not decision too a lot, yet in a temperate us of a, if the water is from the faucet, it would nicely be a lot less warm and the fish is way less tolerant. it truly is extra suggested if the fish are tropicals as hostile to gold fish that are chilly water fish. besides, you by no skill clean a tank employing cleansing soap and water till something undesirable has occurred consisting of the tank being poisonous as a results of useless fish rotting there and then the drastic degree is to take out each little thing, and wash with warmth water and upload chemical compounds to kill off the germs, then wash the sand and pour it again. it would nevertheless be extra ideal to leave the water status for 2 days to settle earlier the fish flow again.

Answer 4

"The fish" as in more than one? Uhhh hate to break it to you.... Betta especially the males don't get along with any other betta. The foam is most likely a bubble nest* built by a male betta. At best a male and female who are put together will mate, produce 100+ offspring then the male will try to drive off the female with often lethal results, after the fry hatch and start swimming the male will eat them.

*Note that a bubble nest doesn't mean a male betta is lonely, or wants a mate. Male betta are loners by nature.

Answer 5

i have had fish tank for 28 years and know a little on this subject more than likely you have a high or low ph balance and or high ammonia you should also have a bubble airiator to produce exta oxygen not just for the fish but it help keep the water clean and sprinkle a little carbon in the gravel if they are in bowls other wise larger tank should have filters wich come with carbon and betas absolutely can not be together they will kill one another

Answer 6

Male bettas build up egg nests to attract the female for mating. Since male bettas don't get along with other fish and are very territorial, they mate with the female betta, get rid of her after the eggs are laid and take care of the eggs themselves.

Answer 7

Betta's breed and the male puts the fertilized eggs in a bubble nest. he cares for the eggs until they hatch (and for a while afterwords). once the male has bread with the female it is important to remove her (he will kill her when he is done)

Answer 8

Betta's build bubble nests for thier young... http://en.wikipedia.org/wiki/Bubble_nest

Also, since the betta obtains oxygen from the air, the tank must not be covered with an air-tight lid and the betta must be able to easily reach the surface. http://en.wikipedia.org/wiki/Siamese_fighting_fish

Answer 9

NEVER EVER PUT A FEMALE AND A MALE BETA FISH TOGETHER, OTHERWISE THE MALE WILL KILL HER!!! Trust me know by experiance.
