So, my poor beta has developed fin rot, after looking for ways to better help him I was lead to Fritz Maracyn. On the back of the box it says it can negatively effect beneficial bacteria, though on an aquarium co-op video the lady said it is fine to not use a qt tank as it won’t negatively effect your bb. So I’m unsure if it will be fine just treating him in his tank?
Any and all advice is appreciated I’ve had my boy for a year and this is my first and hopefully last time dealing with fin rot - Thank you all.
