You can either put water plants in the water or buy those artificial oxygen balls put preferably get a water plant like elodea moss that would make great plants
Leaves give oxygen, leave are in water. Such as algae, therefore you have oxygen for fish.
i recommend that you have a filtration system in the bowl as during the day plants will give off oxygen while it photosynthasises but at night it gives off gasses and the fish needs to the oxygen to breath. the plant will not be enough for the fish and if you do not have the room for a basic filtration system then the bowl is to small for the fish
air pumps or filters
It is oxygen.
to supply oxygen to the water also to give shade to the fish
No, not at all. Most fish extract the oxygen that is dissolved in the water, not the oxygen that is bound to hydrogen in the formation of water. This is one reason that most aquariums have an aerator bubbling away - it is adding oxygen to be dissolved by the water.
yes they take in co2 and give out oxygen, therefore oxygenating the water and helping your fish breathe.
yes they do because they suck in carbon dioxide then turn it into oxygen if they didnt then sirtan types of fish would die out. yes they do because they suck in carbon dioxide then turn it into oxygen if they didnt then sirtan types of fish would die out.
fish swim for oxygen.
Myoglobin is synthesized in muscle cells and imparts the reddish-brown color of skeletal muscle tissue. Like hemoglobin, myoglobin can combine loosely with oxygen. This ability to temporarily store oxygen reduces a muscle's requirement for a continuous blood supply during muscular contraction.
I think when they receive carbon dioxide
Of course all fish need oxygen even puffer fish....
