When I had Angels they were the same way! Always at the top or near the glass beggin for food if I was around. The pigs made it hard to feed the rest of the fish. Though they are soo pretty as your are! Love the video and thanks for sharing!
I tend to be a little heavy handed on my feeding to make sure everyone gets food. Although all the tetras are good on picking up on the feeding cues. I do keep a careful eye to make sure no one is looking like they are eating too much. Going to try hand feeding blood worms this weekend, will see how long it takes them to catch on :)
