My fish are getting friendlier

My fish sure look like they're getting friendlier this morning, at least the bigger ones. I have about three smaller orange coloured (pale orange)  fish which are of a different species and they remain very shy. One of the pale orange fish can be seen in the last photo. They are  very fast and you can only see a blurred orange when they surface very quickly to snatch the pellets and down they go again like a bullet.
