Ok, originally this post was much, much longer, but I thought more people might help me out if I just gave a brief summary:
Situation: New ADF was/is dying because the nitrates/nitrites are waaay too high. I did a water change.
Problem: I did the water change with COLD water. Was not thinking. Poured right in on fish. Nearly killed everyone. Bad. Bad. Bad. Managed to rescue everyone out of tank as quickly as possible. No deaths. ADF still in bad shape. However, everyone was moved to temporary yet warmer small glasses/bowls.
Question: Can I leave my betta/tetras/adfs in these small bowls over night while the water heats up? (Bonus points if you can tell me how to make my frog get better!)
PS-Always THINK before doing a water change. This was seriously one of the most traumatic moments of my life. I swear I saw a tetra silently scream...
