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.
The fish are drinking it. Get rid of the fish
In an aquarium, fish waste and uneaten food release ammonia. The beneficial bacteria then convert the ammonia into nitrites, which are further converted into nitrates. Plants in the aquarium can utilize these nitrates for growth, completing the nitrogen cycle.
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'.
Leaving a dead fish in the tank can lead to an increase in ammonia levels as the fish decomposes, which can harm other fish and plants in the aquarium. This can disrupt the balance of the ecosystem, potentially leading to illness or death of other aquatic life. It is important to promptly remove any dead fish from the tank to maintain a healthy aquarium environment.
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.
Several factors can contribute to the death of fish in an aquarium, including poor water quality, improper temperature, overfeeding, lack of oxygen, aggressive tank mates, and diseases. Specific factors that can kill a fish in an aquarium include ammonia and nitrite spikes, high levels of nitrate, sudden changes in water parameters, inadequate filtration, and stress from overcrowding or incompatible tank mates. Regular water testing, proper maintenance, and monitoring fish behavior can help prevent these issues and ensure the health and well-being of aquarium 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.
