Those are truly beauties, definitely the Sumatran type which I am pretty sure is Luciocephalus pulcher aura.
Here is an article I think I posted a link to before but this time it is translated (badly) from the German original. http://translate.google.com/transla...t&prev=/search?q=luciocephalus&hl=en&lr=&sa=G
They are the worlds strangest gourami!
I can picture a heavily planted 65 gallon long (48"x18"x17") containing some of those, some Belonesox belizanus, a couple leopard ctenopomas, and a few whiptail cats.
You can make a video of them feeding if you want to, but they are so fast all you will see is feeder fish disappearing! What did you do to condition the water ?
