Hi all
This morning I did a large water change to my 24 liters cube where I have 20 red cherry shrimps, 3 adult endlers and +12 endler fry. I changed more or less 12 liters, which is the normal volume of water I change once or twice weekly. It is a low tech, no carbon enriched, low light and once a week dosed tank.
When I did the change all the shrimps became crazy, doing weird things such as swimming up, jumping, then falling on their back... I would say they were suffering. Some of them looked actually dead. Endler adults and fry seemed not to be bothered. It is quite strange because for the first time I let the (tap) water rest for 48 hours with its amount of water conditioning (I normally fill a bucket with tap water, add in that moment the conditioner, wait for 5 minutes and add the water to the tank). When I saw this behaviour I quickly did another 10 liter water change, but this time adding the conditioner to the tap water and without waiting at all. Water temperature from the tap is quite similar to water temperature in the tank, so I think it cannot be a thermal shock.
Luckily, now all the shrimps are doing well and it seems that all of them survived but I cannot understand the reason...
Any idea of what happened?
