Info on Angel fish for a friend?

[babyk]

I have a question... well a few actually

My friend really wants an angel fish bc she thinks they are pretty. She just wants one...I have been trying to tell her fish are harder than they look but if i could get some advice from people who actually have angel fish that would be great:)
So
Do they need to be in a school of fish?
How many gallons would one need? (10?)

And if there is any other info I would need please let me know:)

All I know is that angels get huge when fully, and two adults will need something like a minimum amount of 25 gallons. Their tanks should be tall, apparently a minimum of 20 inches, and they also like horizontal swimming space. She'd probably want to cycle the tank, and tank mates shouldn't be fin nippers or small (enough to fit in the angels' mouths). Get her directed to some fish keeping forums. www.tropicalfishkeeping.com is our sister site and could probably give her good info :)

Thank you! I just know she thinks what I thought when I wanted to get my first betta. "Its just a fish. Put it in a bowl and fed it..."
So not the case.
