hand feeding

Hi MFKers I already had the first trys getting my poly pack used to hand feeding...but until now i only had success, if i put my hand lower then the half of the tank...but i would like to feed them near the surface (no wet arm every time^^). Has anyone of you experience in getting bichirs used...

I hope they don’t mind if I share their video. This would be a bucket list thing for me. To swim with these fish and hand feed some of them. It’s just amazing to me.
