Been watching the midas and see a little stringy poo. His mouth is looking a bit strange too. Not quite like the issues madness was having with the dovii, but it looks strange.
Just found it online, looks like the symptoms are just beginning for cottonmouth. This may have been what happened to the argentea. I had noticed a small patch on her side where it looked like she had scraped herself, it got a small touch of cotton like growth on it but soon went away with my regular water changes, so I thought nothing of it. Everything seems to fit with this fungus. I gravel vac regularly and water change also so I dont know why I have this going on in the tank.
