Injury To Cory?

Hello all,

I noticed one of my corys has a reddish patch by her tail.
She is behaving normally, is it anything to worry about?

Parameters (75 gallon)
ammonia 0ppm
nitrite 0ppm
nitrate 10ppm
GH 4ppm
pH 7.0
temp. 78F

 

Mmmmm see what you mean but doesn't ring a bell. How long are they in there ?

I’ve had them for months, they where about 3/4” when I got them and that particular Cory is about 2 1/2’’. Maybe she just scratched herself on something?
