I have to warn... I just took a LOT of pics.
Very happy though because my tank went through a rough period and came out of it ok. About the same time that I got the Duss, I also set up my other 2 MH lights. After getting the fish and the lights running, things seemed to go a bit haywire for a while. The Duss was aggressive with all the other tangs but was seeing the worst of the fights. He started showing abrasions on his scales. Then my hippo got a couple spots of ich. Then my naso seemed to get stressed and was swimming nervously... even stopped eating for a couple days. Fortunately after a brief period, everything stabilized again and things are now very good in my tank.
The first pics are the 3 phases of lighting, (besides moonlights at night)...
