i have a pair of jack dempsey fish male and female, i did like 10% water change night before i woke up next day and the female is upside down but living for 2 days so far, iam about sure it has nothing to do with water change the rest of fish are just fine, iam about sure shes gonna die i hope not but iam thinking she full of eggs and cant get them out, theres no marks on her from other fish attacks plus she queen of castle nothin messes with her but male, and shes on bottom and almost out of strength so i know shes gonna go but i will keep her in there til last breath do any of u have any ideas what it can be or if i can save her
