I recently got some ADFs to go in my tank, about 2 days ago, and in that two days my betta has about 6 tears in his fin, not sure if its not fin rot. I'm wondering if the ADFs can do that to him, or if its the silk plants I recently got as week, about 2 months ago, I have a few plastic ones but they have been with him along time.
Just wondering what might of caused it and how i find out. and do i need to isolate him and medicate him for his fins to heal?
