Ya Video is a great way to archive your polys. It's great when years later u can just locate on Youtube. Start an account there and past it in the media tab next to image. Cuz we all know u can post pictures, lol.....
As for Poly going up to feed on floating pellets. Some will do it if curious. I have both Voltas that will do it all the time. More so, if I skip a day or two. Faranah Dabola will come up if I dangle a piece of tilapia. My PBB will go up for pellets as well if hungry enough.
