I took some time on Wednesday, July 27th, 2011, and Thursday (the 28th) to shoot these two videos that better show the behavior of this pair during daylight hours.  The first, from the 27th, was towards late evening when I find these fish rather retiring and shy – I had to use Nutramar Ova to get them more active.  The second was more mid-day on Thursday, a time at which the fish are more out and about.  ONE very interesting side note before I close with the two videos.  Thursday evening, while feeding our son dinner, I noticed both the PNG WS Male, and the Lightning Maroon, briefly engage in nest site cleaning behavior, nipping at the back wall of the tank.  Of course, that could mean anything.
On to the vids:
