The process by which water in a fish tank disappears over time is primarily due to evaporation. As water is exposed to air, it gradually changes from a liquid to a gas and escapes into the atmosphere. Additionally, water can be lost through processes such as splashing, filtration, and absorption by substrate or decorations in the tank. Regular water evaporation requires periodic topping off to maintain appropriate water levels for the health of the fish and aquatic plants.
By evaporation water from a container disappear.
Fish use their gills to extract oxygen from water for respiration. As water passes over the gills, oxygen diffuses from the water into the fish's blood, while carbon dioxide diffuses out. This process is essential for the fish to obtain the oxygen necessary for survival.
Fish breathe underwater by extracting oxygen from the water through their gills. As water passes over the gills, oxygen is absorbed into the fish's bloodstream, while carbon dioxide is released back into the water. This process allows fish to extract the oxygen they need to survive in their aquatic environment.
It is not swallowing the water (swallow means passing it to its stomach), it is gulping as part of the process of passing water over it gills. The motion you see as swallowing is in fact the fish breathing. Obviously therefore it does this all the time.
Fish pass water over their 'gills' the gills extract oxygen from the water.
Fish breathe underwater using their gills. As water passes over their gills, oxygen is absorbed from the water and carbon dioxide is released. This process allows fish to extract oxygen from the water and breathe efficiently.
Fish have gills, as they swim water passes over the gills and extract oxygen from the water.
The water will evporate on its own over time.
Freshwater fish do not actively drink water, but absorb the water through their skin and gills. On the other hand, saltwater fish do actively drink sea water. Their gills process the water and take out the salt. yah yah watev. no 1 cares and if u do whatev 2 C
Bony fish use a process called buccal pumping to draw water into their mouths. By expanding their buccal cavity, they create a negative pressure which pulls water in. This helps them breathe by passing water over their gills for oxygen exchange.
The process of repeated evaporation and condensation is call the water cycle.
There are a couple of things you can do to control the pH of the water for tropical fish. You can for example drain the water and start over.
