How do I get rid of hydra in my fry tank, my current batch of peacock gudgeon seem to be too big for the hydra to catch but I have eggs that should be hatching out today or tomorrow and they will be munched, what do I do
Fenbendazole is what I've seen people use. You can pick it up at your local LFS in the dog medicine section. It's a dewormer. It should come in a powder I believe. Then you mix it as per instructions on the forums or if you google it. I think it's only bad for inverts.
