How do I get rid of bubbles in my tank?

Question

My beta fish tank is producing lots of bubbles at the top, the best way to describe them is like soap bubbles only I KNOW there isn't any soap, it seems to help them disappear if I open the lid to the tank for a few minutes. What are they and are they harming my beta? What's the best way to prevent them?

I don't think the bubbles are from my beta, I think they're from the filter system, there are too many of them to be from my beta, my previous beta never had this many bubbles...

Answer 1

The bubbles are actually being produced by your Betta. Betta's are in a group of fish called Labyrinth Fish. They have a separate mucous lined cavity behind their mouths which helps them get oxygen from the air and make those bubble nests that you see your Betta making. It's called a bubble nest because when labyrinth fish breed the eggs are carried by the male and gingerly placed in the bubble nest where he cares for them until they hatch and the babies swim away from the comfort of the nest. The site of the nest means you have a happy, healthy, sexually mature male Betta.

Answer 2

there not harmful, i just means that it wants babies. what you do is take the male out with the bubbles unharmed, then put the female and then it might take a week but when the babies are born, put the male back in the tank, or the female will eat them. Or to be on the safe side, put the babies in a separate tank from the male and female.

Answer 3

This is normal behaviour for a happy, healthy male betta; he's creating himself a bubble nest. If he were to spawn with a female, he would keep the eggs in those bubbles to protect them and tend to them.

Answer 4

most likely it is from your betta. my whole tank top is covered from my betta making a nest this breeding season.
