Yes, that is sunlight that you see in the back of the bunch. You'll notice the tea color of the water... that's from an Indian Almond Leaf in the tank. Another few days and the first couple will be transferred to the regular kuhli tank.
I might add that this particular dealer is very caring about his fish and won't sell anything that looks bad. He imports all sorts of things and if you're interested in joining his group or looking at his site, just drop me an email. He told us that these guys looked good when they arrived and had them in his tanks almost 2 weeks before shipping them to me.
