The betta spits bubbles because it wants to reproduce. This is the habit of betta fish, when in heat, when they want to reproduce, they will spit bubbles. Most of the bubble-spitting bettas are males, but a small number of females have a bubble-spitting habit. The bubbles they spit out will build bubble nests, which can be used to reproduce. In addition, other fish spit bubbles may also be due to lack of oxygen. But the gills of fighting fish can directly absorb oxygen in the air, in the case of insufficient dissolved oxygen in the water, they will float to the surface to breathe, so they will not spit bubbles because of lack of oxygen.
1, breeding: This is the most recommended solution. Prepare a female fish that is about the size of the male and is also in estrus. About two days after the male begins to bubble, place the female in the tank. Then slowly maintain them, trying not to disturb them during the period. After 1, the female fish will ovulate. After the female fish ovulates, the female fish can be fished out, but the male fish should not be fished out, and it should be responsible for taking care of the fertilized eggs. Wait until the fertilized eggs hatch and the young fish begin to swim flat before pulling out the male fish.
2. Break the bubble: This is a less recommended solution. But if you don't want the fish to reproduce, you can also use this method to solve the problem. The specific way is to blow air into the fish tank and break the bubble nest built by the fighting fish. After a few iterations, the fighting fish will no longer spit bubbles.
