I haven't taken biology yet, I'm only going into 6th grade! lol.
Well then learn some of this stuff and when you get to 10th grade or whenever they teach Bio now, you'll be ahead of the game. Bacteria does best when its warm and moist...it multiplies faster and has a faster metabolism when its warmer, but if it gets above a certain high temp it dies. Also, as it gets cooler its metabolic rate slows down (just like most living things) but if it gets below a certain point it dies. SO with Biospira...the reason it works so well is because the bacteria is kept cool so it doesn't eat itself out of food and die in the package, but if it were frozen it would die.
I'm sure what you had head before was that people need to make sure that the biospira they get has been refrigerated, kept cool...because if it hasn't then it hasn't been handled to the manufacturer's reccomendations and will probably not work in the way it was supposed to.
Lorazoo...in general angels (or most other fish) will not eat what can't fit into their mouth. So the chance of an angel actually eating a danio is pretty slim unless you have a full grown angel and add danio fry or something. If you get a particularly aggressive fish (of any type) it will go after fish...but usually a lone angel does not do this. Sounds like you had a nasty one!
