I managed to get a couple of better pictures of the punctata tonight:
Posing here with a couple of my Hoplarchus psittacus. I have a pair of psittacus in another tank raising fry, and these I'm almost sure have paired off. I'm not sure you can make out the area where they have cleared sand away all the way down to the acrylic. It's a nice area, with the driftwood closing it off...and I've watched them cleaning the driftwood, too, as if in preparation for spawning. The pike is what may turn out to be the "odd man out" of the punctata. Looks like I have a female and 2 males, and this is the smaller of the 2 males.
Best shot I have gotten yet of the punctata! This is the same one as in the picture above. I took one of the dominant male, but it wasn't entirely in focus.
