Black Kuhli Loach changing color

Post by GeorgeSteven » Wed Jun 23, 2021 3:20 am

Hi everyone, I have 2 kuhli loachs that have for the last 2 months been alone in a 10 gallon tank, They both started out black. But one changed to white after about a week. Then a bright red, and back and forth from black white red, sometimes it changes within half an hour. Other times it will stay a color for days. Has anyone ever heard of this? I'll be collecting pictures for the next few days.

That doesn't sound good. What are your water test parameters (ammonia, nitrite & nitrate for starters)? You might try doing more +/or larger water changes, that's always my first go to treatment. Not hard in a 10g. Does the color-changer pangio eat well? Any sores or red gills?

Pics?
