here is the befor and after pics, you can clearly se that she lost alot of color.. shes in a 200L tank with on socolofi, theyr always fighting and he is stronger,its been 2 weeks since i seperate beteen her and the scalofi that was bugging her with a plastic net in the middle of the tank and she still hasnt regain her color but she seems to be ok and continue to try fihting him through the net ,even now..do you have any sugestions what to do? water parameters are 0,0,10 and both of them eating well.
How sure are you that this is a female? Males start out the same colour as females then as they mature the colour fades, yellow turns to brown and eventually black which may be what is happening here. If you're 100% certain it's female, then the fading may down to stress as she's still aware of the socolofi and trying to get to it.
