My tank is recently cycled, and i did my first water change 15/20% of the water. Added Seachem Prime as well as Stability as soon as water filled and kept temp pretty much the same (heater turned on only a few minutes). But as soon as i looked, i had one dead Danio and two others breathing heavily up at the top (looking almost stunned) within an hour, another died. Noting that i have three swimming at the bottom very actively. I did remove two plants that were dying(a little rot as well) Thoughts on this? did i change too much water? maybe removing the plants also changed the water chem?
