cobalt stopped eating

[robxc80]

Hello Everyone,

After a big water change and some decor rearrangement, my cobalt blue started activing differently. I think its due to the new aggression my Red Turq is unleashing on everyone. Previously, the red turq was always swimming with the cobalt.

Not, my cobalt stays hidden, doesn't show interest in food and is no longer acting like itself.

The other 5 discus are acting fine and eating even though they too are being picked on. So i'm trying to figure out what the heck is going on. It drives me crazy.

Please help.

My water parameters are fine with everything at zero except for nitrate which is at 10ppm.

How big is your tank? Frequency of water changes? Is the water aged? What foods do you feed?
