Is the focus changing via your control, or is it some kind of auto-focus?
Also, in the second video, there was clearly a larger catfish, but I don't think I saw too many more of those. How big was that one, and what's the average size of the other fish, CC or bullheads? Also, I'm not sure I could tell if I saw a bullhead or not.
That is neat Now that I look closer, there are a few larger catfish hanging out a little farther below the water surface
