Synodontis Multipunctatus Catfish in African Cichlid Tank

I rarely catch these guys out in the light, as they are nocturnal feeders. The moonlights just came on before the main lights went out for the night, so it must have sparked their interest for food. There are about 15 of them in the 3. 0 to 4. 0 range that live in the darkness of a cave I have for them in my 220g Malawi Male Show Tank. Only Tangs in there. I just saw them out and grabbed the video camera. Best group shot I have seen in the 18 or so plus months they have been in the tank.
