Just found Hydra in my shirmp tank. also have a bunch of snails in there that I use to feed my puffer... I don't think any are nerite, just random snails growing around. Is it safe to dose with fenben? and is it a single dose, no carbon, leave in for 2 days, and water change? or is it easier to just suck them out with a syringe?
I don't know about the snails as my tanks were shrimp only and honestly hydra are probably in places you just don't see. Mine were in plants and I would have never been able to find every last one of them so I chose to dose. Mine took two doses but you will see them unhappy after just one dose and their numbers decrease. I saw no affects on shrimp but I only have cherries.
