fenbendazole and nerites
I dosed my 29gal aquarium with fenbendazole because I had planaria (yuck!). I moved my nerites out of this aquarium prior to dosing because I heard they were sensitive. After I dosed, I waited 3 days, did a 50% water change, and moved the nerites back.
2 days after their return to my 29gal, they were looking rough. They just weren't moving around the tank much at all, kind of just hanging out and not eating. So I removed them from the 29gal again. All except one seem okay, just slow.
I really want them in the 29gal, but I am afraid it will kill them. Is there anything else I can do? Will another water change be enough to make it safe for them??
