I love how much more like snakes P. anguillaris look than any other Kuhli. If the head is in the shot, they always look like pythons on the move - perhaps they have wider jaws to accommodate their small size... Anyway, they have a certain look that I love. I have four in the Kuhli/sid tank, but photo ops are extremely rare. I usually only see them when I'm cleaning the tank.
Insightful observations Mark, I agree, or perhaps one of those snakes that live in the ocean....interesting stuff.
Mine were definetly never out and about, alwats hiding under some slate or bogwood.
