I have these grey flat worms. Hit them with a 3x dose of flat worm exit. A few die but majority are resistant. Any ideas what they are and how to get rid of them? I have a sixline wrasse and a springer damsel. Neither seem to eat them.
here’s some photos: I he green mushrooms are covered. There’s a few on the orange mushroom and some zoas. Last photo is the tank they are in. It’s plumbed I to my main display- main display I see no signs of them. I have a green Coris wrasse in there ?
