Ive Just bought 6 neon tropical fiht around 3 weeks ago,along with other small fish, they all died any idears?

Answer 1

First thing to do is check your water

Answer 2

Did you cycle the fish tank first? In the wild, and in established tanks, there are nitrifying bacteria that break down toxic ammonia from fish waste and excess food into less toxic nitrates. In a brand new tank, these bacteria don't exist, so any fish in the tank will produce ammonia, which, not being broken down by bacteria, will kill or weaken the fish. So, of course, it is vital to cycle your tank.
There are a few methods. Do you have access to an established tank? These bacteria live in the gravel and in the filter cartridge, so if you can get some from another tank, you can put the bacteria right into your tank (don't let the gravel or filter cartridge dry out). If you do this, in a day or two, your tank will be A OK.
Another way is to get Bio-Spira. It is the actual live bacteria in a little pouch, and your tank will instantly be ready for fish.http://fishstoretn.com/bio_spira.html
You can also put a source of ammonia into the tank, such as fish food every few days, or a piece of shrimp. You can also use a fish as a source of ammonia, but I don't recommend this - it borders on animal cruelty. Without bio-spira or bacteria from another tank, the bacteria will eventually develop, but it will take at least 2 weeks.

Neon tetras are pretty delicate, and most will not survive the cycling process. However, now, your tank should be almost completely cycled. You can get new fish, but don't get them all at once. Get 1-3 per week until your tank is stocked.

Also, make sure you get enough. A school of tetras needs a minimum of 10 gallons. You also must do weekly water changes of 30% to keep ammonia, nitrite and nitrate levels down.

Your temperature should be 77-79F, and you a normal community flake food should be fine.

Answer 3

Neon`s are pretty hardy fish so you have done something wrong , Did you put them into a new tank without waiting for the tank to mature ? maybe you put to many fish in at once and the filter could`t cope, before you put any more wait a while do pH checks just to make sure the tank is ready

Answer 4

It sounds to me like the tank was not cycled. If the fish were added all at once, then most certainly they died of ammonia or nitrite poisoning. Fish excrete waste just like we do, only it stays in the tank with them. The immediate result is Ammonia build up.

The cycle works like this: Fish poo = ammonia, Bacteria1 breaks down Ammonia into nitrIte, Bacteria2 breaks down nitrIte, into nitrAte.

Once there is enough bacteria to continually break down the constant flow of ammonia and nitrites produced by the fish's waste, and leftover food, the tank 'cycle' is then complete. Without the bacteria present to break down the ammonia and nitrites, the fish would surely die.

If you want to try again, I would recommend adding one fish at a time, two max.

Answer 5

Could be pH, Amonia(sp)

would have been good to provide a little more info.

What size tank, how many filters and what type? New tank?

And as mentioned above, take a water sample to your nearest pet shop or whatever. They will probably test for free and give you guidance.

Answer 6

had the same problem too many fish to quick before the tank is ready, try putting a couple in then leave it for a couple of weeks then add a couple more do it that way

Answer 7

Test your water. Fish usually die as a result of nitrite or an acid PH.

Answer 8

how long was tank set up. before you added fish.you should only put a couple in at a time. so filter can build up bacteria.have you done water test.is the temperature right.plus is tank right size.hope this help.s you.

Answer 9

Most likely they died due to ammonia, nitrite, and/or nitrate poisoning, Read up on the nitrogen cycle.

Answer 10

sometimes you have to make sure your fish tank is mature enough if its not then some fish die i set my tank up and left it for 3 weeks then i brought my silver sharks red fin sharks angel fish iv had them for 1yrs now and they are healthy and big

Answer 11

There could be several reasons. You would do better to discuss this with an aquatics centre, before you get anymore, to see if they have any suggestions.
