There was a slight improvement of behavior after the dip, but that only lasted for around a day. I really hope it is flukes, because that would probably be easiest to treat, especially compared to a protozoan or internal disease.I have a hard time believing Luxo would be affected by aggression. I feel like she would just turn full blown satan and take that angel out. Hopefully it’s something easy to treat like flukes and the treatment is effective. I think I saw you said you tried fresh water dips on them, was there any improvement after the dips, even if it went back?
