it's dead!
Simple observation will indicate if the Betta is making bubbles. You will see them at the surface of the water.
Betta fish can simply rest at the surface of the water or they may rest on leaves of plants.
Male bettas blow a cluster of bubbles that float on the surface of the water.
The film on your betta fish tank is likely due to a buildup of oils, proteins, and other organic materials on the water's surface. This can be caused by overfeeding, lack of water circulation, or inadequate tank maintenance. Regular water changes and surface agitation can help prevent and remove the film.
Bettas breathe air from the surface of their bowl so it really depends on the humidity of the area that the betta is in when it is out of its bowl. If the betta's body stays well moisturized I'm convinced they can at least live two days out of water (conditions permitting).
The male Betta builds a bubble nest at the surface of the water. The ova(eggs) are fertilised under the nest then collected by the male in his mouth as they sink. He then places them in the nest where he tends them.
Signs that your betta fish may be dying include lethargy, loss of appetite, faded coloration, fin deterioration, gasping at the water's surface, and unusual swimming behavior. It is important to monitor your betta closely and consult a veterinarian if you notice these symptoms.
The film on top of your betta tank is likely caused by a buildup of organic waste and oils. To prevent it, you can try increasing surface agitation with a filter or air stone, doing regular water changes, and avoiding overfeeding your betta.
The question seems poorly worded, but Earth is the planet with liquid water on its surface.
Place a tablespoon of salt in the tank make sure the water is clean
Betta's are a very strange type of fish. For most fish putting them into previously boiled water would kill them, boiling water removes the oxygen vital for life. However, Betta have a special organ that lets them breath atmospheric air. Which means every now and then bettas will go up to the surface to get air. So maybe there is a chance of a BETTA surviving since it would not rely on the air in the water.
