Fishing Dieing

[Krishs Bettas]

Hi,

I brought about 15 cardinal tetras about a week ago.
My tanks has been mature for 5 years.
The were alright on the first day and then the next day began to die one by one everyday.
Before the die they seem to swim wirdy.
There were no sighn of disease before they died.

PH 7
Ammonia 0
Nirtites 0

how long have them been in the bag before shop and tank?

When you state - they are swimming weirdy - is it like a death role - across the tank / up and down whilst rolling.

If so my first thought are your Co2 levels if you are injecting Co2 and if your levels are high this will affect them getting acclimatized to your water parameters.
