Hi all,
I just had 2 of my 4 zebra danios die very quickly after a water change, and I was wondering if anyone had thoughts as to why.
What I did was siphon 30% of my water using a Python. Then I replaced it with tap water at the same temp as the aquarium (about 77 deg F). Immediately after that, I added about 2ml of Seachem Prime to neutralize the chloramine from the tap water.
A minute or so after adding the Prime, I noticed two of my zebra danios were doing loop-de-loops and they were dead within minutes. The other two zebra danios were fine! And I also have about 20 other fish (various species) and they were all fine as well.
My theory is that the zebras gulped some of the Prime before it could diffuse into the aquarium.
This is a 55gal tank that has been setup for about 2 months. I did the larger water change because I haven't been doing frequent smaller water changes and I was trying to address some of my plants getting brown/black leaves (thought the issue might be iron phosphate).
BTW, the water parameters were all pretty good before the water change. PH is 6.8, ammonia is 0, nitrite is 0, and nitrate is 10ppm.
Thanks,
Jason
