Hi,
I've often heard that angels eat neons especially if they're young neons. But in my experience my angels have never eaten any of my neons. I have a school of over 15 neons. And 5 angels along with a bunch of other tetras, cory cats, platies ect. All the neons are alive... My female angel hasn't bothered eating any of them. Maybe it's because she's so well fed. Who knows. But I've never had a problem.
