My Female Fighter Has Lost Half Its Colouring

Sorry for the shoddy picture, but its taken with my phone for quickness sake...



Tank details: tanks been running for over 6 months, 60 Litre, containing 4 female fighters, she seems to have lost her colour in the last half an hour - all water tests are coming up within range, and i did a partial change (10% last night)? and all of a sudden, the other females are picking on her which usually never happens... is she just stressed out, or could it be something more serious?

thanks

They lose their colour when they are stressed and she had stress stripes ideally you should have at least 5 females to spread the agression. I've never seen one lose colour like that though, half like that.

Try changing around the aquarium decor that sometimes helps. Is there a main bully?

There doesn't seem to be a main bully, and there never usually aggressive

It wouldn't be a bad idea to move her into a hospital tank and see how things go. At the very least, it'll keep her from being bullied and stressed even more.
