Hello! I have a koi female baby betta girl, and she changed all the color in the span of 2 days….
No changes to my water parameters:
Ammonia: 0, Nitrate 10, Nitrite 0, ph 6.8, kh 3, gh 6, temp 76-78F
I noticed a white patch on her spine on Saturday, it was even worse yesterday. Today she looks like a completely different fish.
There is no sign of injury, infection etc. She is sitting at the bottom of the tank more.
There are 6 kuhli loaches and 6 sterbai corys in a tank, but she always lived in a community setup.
