Then your filter is not on.
You are supposed to have bubbles in your fish tank or else your fish will die because they don't have enough oxygen.
Fish make bubbles at the top of the tank because they release excess air from their swim bladders, which helps them regulate their buoyancy and stay afloat in the water.
Are you sure they're bubbles and not eggs? If they're bubbles the it is just from your filter putting bubbles in the water.
is named bubbles and is a yellow tang.
The machine used in fish tanks that makes bubbles is called an air pump or air stone. It add oxygen to the water and keeps the oils from coating the tank.
The purpose of an aerator in a fish tank is to increase the surface are of the water next to the oxygen source to allow a more efficient transport of oxygen from the air to the water for the fish to be able to breath. A few large bubbles have less overall surface area than many small bubbles.
The bubbles on top of a goldfish tank help to oxygenate the water, which is important for the health and well-being of the fish. Oxygen is essential for the fish to breathe and for other biological processes to occur in the water. The bubbles also help to circulate the water, preventing stagnation and maintaining a healthy environment for the fish.
in a tank or the ocean?
The bubbles you see are only excess air that has been deposited on the surfaces in the tank. They are perfectly normal and will dissappear in time.
It means absolutely nothing. I hope you also have a filter connected up to the air pump because bubbles do absolutely nothing to help your water quality. A cycled filter is essential in every occupied fish tank.
There not really eating them they are trying to get the oxygen out of them so that they can survive if they are doing this unless they are a betta fish it probably means there isnt enough oxygen in the tank for them which usually happens if you have a fish in a tank to small for it or have to many fish in one tank you probably want to upgrade your tank or get rid of some fish if they are doing this. Also if you dont have a filter for the tank get one! it will help add oxygen to the water and is necessary for almost any fish to survive.
It dies
