Hi guys, just a little quick info: my 29 gallon tank has 3 sailfin mollies, 3 koi swordtails, 5 panda platys, 1 painted platy, 3 blue platies, and a mystery snail.

Last night I did about a 20% water change that I do about once a week. This time I ended up waiting two weeks because I was busy. I dechlorinated the water and added some aquarium salt--all things that I normally do. Immediately after the change the fish were fine, swimming around happily like they always do afterwards.

But then a couple hours later I noticed they all seemed sluggish--some were near the top, some were near the bottom. My weaker male molly died today.

I took out some water to increase the oxygen flow and they seem a bit better but not 100%. All water tests were normal (0ppm) and the ph is about 7.8.

Any thoughts/help?
