Just a note, I checked her again and she had a piece of substrate in her nose, I got it out so hopefully that was what was causing it. I'll keep an eye on her. On a side note, in one of Brian Barczyk's videos he mentions that you can use some diluted F10 to make a vapo chamber for ball pythons and that that can help kill of any RI that is forming. Has anyone tried this with Retics?
