Hey guys, noticed some fin rot/ damage on my flagtail. Not sure if it’s fin rot as it hasn’t progressed or recovered in 2/3 weeks. He’s in the tank with an aggressive indonesian tiger fish which I suspect is dishing some damage as I wake up some mornings to a few loose scales but nothing serious. Don’t want to unnecessarily treat the tank so would like some second opinions if it’s fin rot. Thanks a bunch!

The Flagtail will never heal because the Datnoid will continue to harass it. Btw doesn't look like fin rot. I recommend rehoming the Flagtail.

Agree with that. Flagtail anail fin will heal completely and fairly quickly in another tank without constant harassment.

Thanks for the feedback everyone! I’ll try to leave it in for a bit more as I’ve only got 4 fish in a 350G. Will try to add some decorations as distractions as it’s a bare bottom tank.
