My daughter's molly tank (source of Polypterus food 
) has suffered a few casualties in the past few days. The fish become bent into an S shape, have trouble swimming, then die. It seems to effect 1 fish, then another, but never the whole tank at once.
I haven't tested the water param's yet, but we do weekly 25% water changes, and overcrowding isn't an issue.
Any thoughts?
