hi all one of my female Betta's has red worms hanging from underneath her from the anus, she is now in quarantine, i think this is thread worms IE nematodes any way of getting rid of the beggar's and should i treat the main tank i have done a 100% water change in the main tank has any one else had this and had the fish survive as have read up on them and it don't sound good for her but i dont want to loose her so any help would be better than no help at all, ,,,,,,,,,,
