We got a fish from a friend and later discovered that he was more carnivorous than we had anticipated. We had been feeding him 50-100 fish for a while, but we decided to just go all out with 500. I filmed the release of the creatures with an upside down go-pro (Hero3+ Black for anyone who cares) in 720/120fps and then rotated and retimed the footage.
Sorry if I didn't edit the video enough to your likings. There wasn't much to work with, and I felt it did a pretty decent job portraying the moment on its own.
