No, fish cannot survive in milk as it does not provide the necessary oxygen and nutrients for them to live. Fish need water to breathe and milk would not be a suitable environment for them to survive.
Well, water for a start. If you don't have that, you're kind of screwed. But it all depends on the kind of fish. There are 4 main types of fish: coldwater, tropical, saltwater and marine. A filter is important as well. It removes impurities in the water and little bits of food as well. A heater is needed for tropical fish as they're used to much warmer water. Food would also be a good thing to have! Just get normal fish flakes, not the tablets. Some oxygen stones would be useful, but they're not necessary. A 10% water change is a good thing to do every week as well; it just freshens up the aquarium. You can change the water with a hand siphon; your local pet shop might have one. A net is used for moving the fish into a different container whilst you clean the aquarium. You should also consider a hell of a lot of water treatments as well, because fish can get lots of diseases. Anti-fungus, Anti-fin and tail rot, anchorworm treatment etc. are just some I can think of off the top of my head. A water conditioner is a good purchase as well, to get rid of the chlorine and chloramine as well. WATER TREATMENT IS ESSENTIAL! CHLORAMINE IS DEADLY TO FISH
Whales are mammals, not fish, so they need to come to the surface to breathe air through their blowholes. They cannot extract oxygen from water like fish can through their gills.
Fish cannot live out of water because they rely on water to breathe. Fish have gills that extract oxygen from water, and without water, they are unable to get the oxygen they need to survive. Additionally, their bodies are adapted to the buoyancy and support provided by water, so being out of water puts stress on their organs and can lead to suffocation and death.
Fish have gills- thy are similar to lungs, but water gets pumped through them. Oxygen dissolved in the water transfers (in the gills) to the bloodstream of the fish, and carbon dioxide gets flushed out.
All fish need oxygen....
It is oxygen.
Floran fish need oxygen other wise it will death . so always need oxygen
Kind of. Fish need to breathe water to get oxygen. If they can't breathe, or if the water has too little oxygen dissolved in it, the fish will die from lack of oxygen (I would say suffocate; you may say drown).
All fish, whether baby or older, need oxygen.
Water with oxygen, like any other fish. (except for the African lung fish) I'm not sure what kinds of water you're choosing from.
Of course all fish need oxygen even puffer fish....
Gills carry oxygen fish need directly from the water
Jelly fish
it doesnt need air
it depends on the fish.
Depends on the fish.
