Despite soaking plants in hydrogen peroxide, it seems they have introduced planaria into my fish tank. It is a 60 litre with one betta. I have some liquid panacur on the way but I wanted to ask if I had to put my betta in a quarantine tank while using the panacur? The quarantine tank has not been cycled so I am concerned she may become unwell in it. Also, how to I remove the planaria out of her sponge filter? I do not want to lose any beneficial bacteria. Thank you for reading.
