Here is my black damsel, I call him herbert and his mannerism's remind me of the yellow tang on nemo. He comes out of his cave on the left side of the tank and swims under the heater for about 2 seconds then drifts out into the maxi-jet 900 interstate and shots across to the return from the skimmer and proceeds to roll around like a dog in the micro bubbles that are created. Lets just say he rides the little yellow bus to school.....hehe
