Cherry Barbs, Blue Paradise, Rainbow Shark, Panda Cory, Tetras (i forget what they are named), ottos and SAE.
I recently tried to add a Dalmation molly to the tank, but it dies which is why I went to get the water test.
I doubt the water pH is the issue. Of all your fish the molly should have done the best with that pH. If none of the other fish are having issues I would not mess with the water chemistry.
What size aquarium do you have?
