I have a 60L tank which I have had running for about 10-12 weeks.
The levels are as follows: pH 7.8, Ni: 0 A: 0 Na: 10

After cycling it for 2 weeks I added 5 Zebra Danios:
All were fine for a week, then 3 died over the next week
(Stopped eating, dwelled in corner of tank doing nothing.)

After 6 weeks I bought 5 neon tetras.
All were fine for a week, then 3 died over the next week
(Stopped eating, dwelled in corner of tank doing nothing.)

I have now bought 3 neons and 3 glo light tetras.
All were fine for a week, 1 has now died and two are looking ropey.

Hmmmmmmmmmmm, anyone see a pattern emerging?
More importantly, anyone got a solution. It seems unusual the original 2 surviving Danios are still fine.

I look forward to your responses.

I am not sure what you can do about it, but when I started I had the same problem. I bought 4 Zebras, and 3 died, then replaced them and 2 died and replaced them and another died. Are the fish that die significantly smaller than the others? The bigger ones could be more aggresive and the littles ones might be stressed. That is just a theory, I am not sure if it is right or not.
Good luck.

Your pH is quite high it could be the problem. I keep my pH at 7.0, your pH level is more suitable for cichlids

Is 2 weeks long enough for a cycle? I don't think that the tank is fully cycled yet. Can you give us the parementers(sp) Tired Shocked

Kjh- You may have a point with the size of the fish, I had noticed it's always the bigger ones that survive, although the big ones don't tend to chase the small ones that much.

As for the tank, it is cycled. All the levels seem okay except the pH

How do I lower the pH???

You can combat the pH by either using peat moss in your filter or getting your hands on some RO water, which when mixed with tap, should soften it and lower your pH.

If you want more info about either, check out the old threads here, there are a ton of them.

I don't now if this helps but are they breathing fast?
for the neons I found that they would hide somewhere and breathe very fast I found that if you lowerd the pH to around 6.7 or 6.5 that they would stop doing it sorry if this didn't have a hint of info and I'm sorry for your loss
