fish need air because they won't be able to breath if they didn't have air,
and fish need air badly because they spend most time in the water. fish need air as much as we do.
because like us they need water to live it's like our air without air we couldn''t survive. So fish need water to survive because it is a basic need
Sounds as if your fish is gulping at the surface. If that is so, you need to install an air bubbler. Your fish is running short of oxygen.
Because they need it. They can't actually breathe out of water so they need things like filters or the back of boats to make air bubbles
Fish do not need air they need Oxygen which is a component of air. Nature always tries to balance things out so the surface of the water (meniscus) allows the transfer of gases. CO2 goes out into the air above and O is absorbed by the water. Plants also make Oxygen and use up Carbon dioxide. The fish have gills in which the membranes do the same thing as our lungs.
you mean how do they? they still do and they affect it badly by eating the native fish's eggs so they won't be able to reproduce.
there are holes in the shoes because you feet need to breathe. They also allow the air to get in so your feet don't sweat so badly. If they didn't have holes your feet would sweat and get hot. One more thing you did not do the right are it is our.
gold fish need oxygen and produce a lot of waste so it is a good idea to use a filter and an air bubbler, or you will have to do much more frequent water changes. Beta fish need less oxygen so they ac live in vases or bowls
no, they have a swim bladder but this is so the fish can stay afloat
water an air pump small with hose to oxinate the water so they can breath filter and water pump
Is your goat too fat? if so then yes, you need anorexia. badly. poor goat :(
Lungs are what air breathing creatures use. That is how they evolved. Gills need to have water flowing over them so they work in water. So Lungs won't work in water and Gills won't work in air.
you don't need to know :)
