I don't know how I missed this thread. Thanks for all the comments!
hooppjs - I used to keep SA cichlids, but much smaller than what you have (German Rams, Keyholes, Bolivian Rams). Nice looking fish you've got there!
Fritz - These guys are a great source of entertainment...it's literally non-stop! To say they're active and aggressive would be an understatement...
Heinrich - I checked out your webpage and your PPG page....21 pics??? I bow in the presence of greatness! BTW, my wife and I were looking at the pics in your family tree. Really interesting. BTW, she's from Germany too.
k100d, spyglass - I use am old Vivitar 3500 flash in manual mode. No polarizers or weird angles. The key is pointing the flash up and using a diffuser. Mine is a homemade DIY job made from some cheap foamies from the craft section in Walmart. It looks pretty much like the one found here:
