They die because they cannot breathe, since they get their oxygen from the water.
Migrate (Alex Shotts)
Either lack of food, or because of the water. there are freshwater fish and saltwater fish. if you get the water mixed up, it could mean the end for little swimmy :(
It will eventually die for lack of adequate air.
If you mean drown then no, fish have gills that extract oxygen from the water as it passes Through their gills but they suffocate when the flow of water stops passing through the gills or there is a lack of oxygen in the water or when brought out of the water
Two reasons 1. Lack of oxygen 2. Through toxins
Oxygen is not insoluble in water: the solubility at 20 0C is 7,6 mg/L.
This is common when there is a lack of Oxygen in the water or a surfeit of poisons caused by either a poorly running filter, overcrowding, or lack of water changes. Fish only gasp at the surface when they are in trouble. First thing to do is a large water change followed by checking out the filter medium to make sure it is not clogged, then count the inches of fish in the tank and compare to the holding capacity. The rule is 1 inch of fish need 1 gallon of water. (2.5cm of fish needs 4.25ltrs water). If you are overstocked then some fish need to be rehoused.
yes they respond very well
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).
The fish is ill and may need to be treated with antibiotics, or the water quality is bad due to lack of maintenance
your fish is turning grey due to lack of protein and lack of proper diet.
Dolphin,fish,whales,octopus,shark.Microorganisms:Blepharisma,Vinegar eels.These are all examples of animals that live in the water.
