Check the nitrates. Clean the tank. Condition the water. Treat for disease.
Remove fish that seem unhappy or distressed or sick. That's all i can give you maybe you need to take logs of everything you do and check with the local peet shop to ensure everything is correct.
It could be any number of aquarium diseases. take a sample of water and the next fish that dies to your local aquarium store and have them looked at.
Ammonia comes from fish waste.
check the pH balance for ammonia
It would die. The ammonia would kill the fish if amounts were elevated.
Ammonia levels should be at zero. Ammonia is never safe to have in an aquarium especially new fish. Transporting a fish generally causes some stress for them and with the addition of a water problem in their new home it could prove fatal. If this is a brand new tank it would be wise to cycle it fully before adding a fish.
Ammonia is a base. To fix it, perhaps try adding buffer to the water. Just as a side note, the ammonia is actually a product of the fish. Fish pee pure ammonia because of the abundance of water in their system.
The fish are drinking it. Get rid of the fish
They do not "show" balance of nature. What could be happening is, your planted aquarium could be a "balanced aquarium" or be in the process of becomming one. In a 'balanced aquarium' the living creatures (fish etc) produce waste products. These products decay and become poisonous (Ammonia). Without a natural balance of other organisms (Bacteria) the living creatures in the tank would all be poisoned by the ammonia. What happens in a balanced aquarium is. The Waste Products produce Decay which produces (deadly) Ammonia. Aerobic bacteria convert Ammonia into (deadly) NitrIte and then into (harmless) NitrAte. The plants can then use up the NitrAte and in the process of photosynthesis, produce Oxygen, some of which is used up by the fish etc. In todays aquaria most of this 'Ammonia to Nitrate' conversion is carried out in a filter that has been 'cycled'. Cycled simply means that the filters' media have suffucient aerobic bacteria to perform this Ammonia to Nitrate 'conversion'.
No, leave the tank for several days, then get your water tested for ammonia and nitrite. Depending on the results, either get a FEW new fish, or let the aquarium run until the ammonia and nitrite are gone.
Sometimes fish die in aquariums when the ammonia level is too high. I recommend taking a sample of the water to a pet store to have it checked for anything wrong. I had fish dying and took mine to have it checked. When I got the levels water problems fixed my fish stopped dying. It could be from high ammonia levels, not enough oxygen, not the right temperature, or a disease or parasite
Get a small Aquarium Fish Net, get the body of the Fish, put it in the toilet.
YES. Ammonia is the mostdetrimentalwaste that you could find in your tank. It can really harm your fish and species. It is all apart of the nitrogen cycle so the bestrecommendationfor high ammonia is to balance out this cycle by doing a water change or adding plants to the aquarium to produce oxygen to aid in the nitrogen cycle.
