My long-finned albino BN is out regardless of lighting conditions. He's very gregarous and will take algae wafers right off the end of a long tong. My regular albino was much more secretive in his previous tank. In a new tank, I got smart and put my driftwood (with "caves" underneath) more toward the front of the tank and not hidden by plants. I now see him all the time because he's in his "cave"
