They even have little red horns!
Man have you ever got UBER flatworms!!!
My flatworms vanished after 1 EXIT tratment and a follow up to be sure......all better for 4mths. The only thing I did out of the ordinary, is siphon every last visible one out before each treatment....hours.....but worth it. (used a filter bag with J-cloth in it over the end of a siphon hose to the sump....and sucked and sucked).
Sooooo I hear Ya and feel YA .....eeeeradicate the little mothers!!!!!
GOOD LUCK!! ...prayers are with you!
PS : you are right,when you burst the suckers with fresh water rinse ....oh my do they stink! (and yuo can see the yellow sh.......t they would have put in the tank upon death)
