A few months back, I bought some danios against my better judgement - their bellies were on the large side. To make a long story short, I now have camallanus in at least three of my five tanks (possibly all five, since I share equipment and I've been moving plants around). Question 1: I want to treat the tanks with levamisole, but I have some sensitive critters in there and I'm not sure what's safe for them. Does anyone know? Here's the list: Hillstream loaches Nerite snails Shrimp (caridina, neocaridina) Axolotls Guppy fry Convict cichlid fry Question 2: Should I euthanize fish that look bloated and/or have worms sticking out? Thanks for your help!
