I've had this female kribensis for about 2 months now. She was a gorgeous bright purple/pink until about 1 1/2 weeks ago. She turned this incredibly drab grey color, and lost all tint to her belly. I tried giving her some blood worms, and other high quality food, but nothing seems to help. The male is still bright, active, and trying to get the females attention, but she just ignores him and either swims away, or just keeps picking at the rocks for food. I really don't know what to do now! Please help! She was so beautiful! What happened??!!
