Scales are just laying flat, nothing changed in her behavior thou it's just the color.
She's a CT, cambodian, and since i got her last August i think she's a cello coz until now i can still see her insides.
tank size is a gallon, temp (no heater), water change schedule is 100% every 3 days, what water additives you use (none) i use purified water, what you feed her - aqueon tropical flakes, a pinch twice a day.
I have a former cambodian whose head has turned red, mouth has turned pure white, and she's getting more and more black scales on her body. It's very exciting to watch her change! So, yes, what looks like a cambodian may not be a cambodian and can definitely change color.
