eat it
also you can see things like tiny bubbles, fungi when it gets big, volvox when its big, basicly everything but it has to be full grown
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.
No. For fish it all depends on size of the tank. that is why you see tiny goldfish in tiny tanks. big goldfish in ponds. and fish the size of a bus in the oceans. Plus it will also depend on the anatomy of a specific fish. Or how much food is readily available.
Alot of times when a betat fish is happy you will see something like spit bubbles at the top if it's angry or upset you wont see these also you might see its side fins around the head go forward
With a good eye you should be able to see the eggs, they look like tiny little bubbles, usually the size of a pin head. They will most likely be stuck to something like a tank ornament or plant in the tank
What you mostly see in the bubbles is steam, which is water in gas form.
If there are big bubbles that pop then it is boiled
you should see a doctor....
When you first start to boil water, the bubbles that you see are basically air bubbles. Technically, these are bubbles formed from the dissolved gases that come out of the solution, so if the water is in a different atmosphere, the bubbles would consist of those gases. Under normal conditions, the first bubbles are mostly nitrogen with oxygen and a bit of argon and carbon dioxide. As you continue heating the water, the molecules gain enough energy to transition from the liquid phase to the gaseous phase. These bubbles are water vapor. When you see water at a "rolling boil," the bubbles are entirely water vapor. Water vapor bubbles start to form on nucleation sites, which are often tiny air bubbles, so as water starts to boil, the bubbles consist of a mixture of air and water vapor.
Most plumbers use a soapy liquid to see if bubbles form.
You would surely be aware if Bettas have been spawing in your tank. If they have, and nothing else has been spawning in there, then in all probablility the tiny fish you can see will be Betta.
Are you getting power to the chlorinating cell. You can see tiny bubbles forming like a fine mist around the elements when they are working.
