I believe one of my SAE has anchor worm. I ordered some Clout and was reading the label thinking i would treat the whole tank since its a parasite.

However, on the label it states it should not be used on scaleless fish bottom feeders and invertebrates (and some others I don't have). I have plecos, kuhlis and assassins in the tank. Plus I'm not sure if you'd classify an SAE as a bottom feeder...

So I do have a tank I can QT fish in. What is the best route here?

Should I remove the unaffected loaches/plecos/snails and treat the main tank?
Should I just remove the SAE and treat him?
Should I go shopping for an alternative medication?
