All 13 of my Neons died within a week.

JordynMurdock

So all of a sudden my Neons started dying. At first I thought it might be a bully fish so I watched them. No abnormal behavior was occurring so I let it be. The next day I came home to 6 dead. Then the next day 2 more. I just found 1 more this morning and the last remaining is acting so weird. He is near the bottom flipping around extremely fast. He will be swimming upside down and then will float to the bottom and sit still but still breathing. He will then go back upright and flip around fast again. I don't know what is going on. Did all my fish die from a disease? The weird thing is none of the others in the tank are dying or acting weird. All the Rummys and Cory's are fine.

I would test your water asap. Just becuase other fish are fine doesn't mean everything is okay with the water :) most places will do it for free if you do not own test strips. Once we know about the water we can go from there...

Tazman

Agreed on getting the water tested, I would stay away from the strip tests and if you haven't got one get an API Freshwater Master kit (liquid tests), they are reliable and easy to use.

Without knowing the water parameters or any obvious sign of disease, it is nearly impossible to say what may have caused your deaths.

Sorry for your losses.

Tazman

If you can post your ammonia, nitrite, nitrate, temperature that might give us somewhere to start in solving this issue.

Hey Tazman, you are probably right becuase i have no idea.. but at my work i test peoples water for their fish tanks with the strips and i find them accurate except for the ph which is alaways like runny? but after testing water for 2 years i know what it means off my heart haha lol .. i heard somewhere that everyones drop is different so the liquid one would be the one that is less accurate? or is it accurate becuase it doesnt matter how big the drop is? ive bever used the liquid one? just wondering..

Well apparently the test strips can be inaccurate due to moisture and humidity. If you invert the little bottles and don't squeeze, just let the drips come, they are pretty uniform.
Jordyn.... most importantly, how long has this tank been set up? and how did you cycle the tank? What size is the tank too?
Sorry for your losses!!

Yes, it is next to impossible to ascertain a problem unless we know all the data. This will repeat what some have already mentinoed, but I'm just going to set out what we need.

Tank size, and what fish (species and numbers) are in it?
Live plants?
How long were the neons in the tank before they started dying?
What are test numbers for ammonia, nitrite and nitrate?
Water temperature?
What is the pH?
What is the hardness of your tap water?
How often are water changes, and how much water?
What is your water conditioner?
Are any other substances aside from the conditioner going in the tank?

Byron.

29g with 7 rummy, 5 Pepper Cory, and now no neons.
No live plants. Had 8 neons for about 2 months. Added 5 more neons then they started dying.
Ammonia 0 nitrate 0 nitrite 0
Ph around 7.0
Water is soft
Weekly 25% water changes
Aqueon conditioner
No other substances in tank

Strange, if the tank has been up for 2 months you should have a NitrAte reading by now....

Byron

Yes, that is odd, with no plants too.

You didn't mention tank temp, but I will assume not above 77-78F. Correct me if this is inaccurate.

This may have come with the new neons. I would have a look at the fish in the store tank where you got the last neons and see if they are diminishing. Visually, but also ask them. This is too co-incidental.
