My friend wants to set up an angelfish tank for her mom for christmas, because those are her mom's favorite fish. Right now she has a 10g that she wants to put them in, but I suggested that it's not a good idea. I know they grow pretty long so they like a taller tank, and that they'd be likely to fight in such a small tank. So what is a good size for a pair of angels? Do they need to be in a school? Anything I'd need to know about angels, I would appreciate learning!
