Last October, I bought six Paracyprichromis Nigrippinnis. For about three months, they all seemed to be thriving, getting along well. I have a 135 gallon tank with a 3-D rock background and lots of rocks and other hiding places on the ground.
In the last two months, four of them have broken off and hang out alone, not at the top of the tank, but alone.
They have turned brownish in color, most likely due to some sort of stress. I removed them and put them in another tank. They were easy to net and didn't react until they felt the netting. The remaining two are flourishing, very active, good color.
The four in the separate tank all hang vertically on the glass at the surface. They don't react to food unless I place it right in their face. And then they pick blindly at the surface until they find a piece of food. They spend 75 percent of the time picking at the water surface where there is no food. I'm convinced they've done blind, but their eyes look normal.
I've never seen this before. Any thoughts?
