Phoenix44, the picture of them is next to my name. I have no idea of their sex but i call the blue one George and the orange one Mildred. Do not know how old they are but i would say George is quite young. Adrienne...I think I better feed them more often and do 2 x cubes of frozen blood worms instead of the one they have been getting. They are a great pair, the first discus i had was very aggressive but this time these two get on extremely well. Perhaps they will breed at some stage.
