Some plecostamus can breathe above water, but I would not suggest keeping one one of water.
fish are fish. if they could breathe above water they would be a mammal. no fish have lungs only.
In the aquarium were water, weed, sunfish, snails, and a neon fish.
No, a filter in an aquarium does not provide oxygen. It helps to clean the water by removing waste and debris, but oxygen is typically added to the water through an air pump or other means to ensure the fish have enough oxygen to breathe.
aquarium means: alot of water surrondering the fish that live in it.
The general rule for stocking a fish tank is 1 inch of fish per gallon of aquarium water.
Fish have evolved to survive in water. If they didnt have water they can't breathe, they dry up and die. Some can live up to 8 hours without water as long as it is on ice. A fish in an aquarium has to have a water pump that supplies air bubbles for oxygen.
They use their gills to breathe under water.
No, saltwater bullheads are fish that require water to breathe using their gills. They do not have the ability to breathe out of water like some other species of fish.
A betta does not breathe air all the time, it is a fish with gills that lives in water, and it certainly looks like a fish. However, they do need to have an air space at the top of an aquarium and can survive in a wet tissue. They are fascinating fish, but they are definitely fish.
The fish are drinking it. Get rid of the fish
Most fish do... unlike the betta fish they can breathe water and air. Dolphins and whales are an example of ones that breathe only air. Sharks, gold fish and other fish have to breathe water.
"Tropical" simply means the aquarium is kept above 60F. "Marine" simply means the water in the aquarium has had sea salt added to make the water into sea water. Therefore it is possible to have aquaria that are "Tropical", or "Marine", and also "Tropical marine".
