I have a question, after a couple of the weekly PWC
that we have done we have had a couple of zebra danio's die on us.
The process we are following is:
1. Using the python we have taken out roughly 40-50% of the water.
2. Add Prime to the tank. (Full Tank dose)
3. Add water back in guestimating the temperature of the water. Prior to PWC
water temps were 78 degrees and after 79-80 degrees.
4. Add Seachem Flourish while the water is filling for the plants.
The only thing I did differently this time is my daughter and I took out the java fern and attached it to a new piece of driftwood with thread. We then put the driftwood in the tank for the first time.
After the PWC
, the Danios sit at the top of the water with their mouths at the top. They eventually turn upside down and die soon after.
Are we doing anything wrong? I have done a lot of reading here and elsewhere since getting the fish and I cannot think of anything?
Any advice would be greatly appreciated!!
