Im thinking of getting a new tank, i wanna do alot of preparation and in no way in a hurry, i was wondering wats a good size tank for keeping just angels in? and wat are their plant/water requirements?, i am looking at websites on the net but i would rather hear good advice from some expierienced angel owners, as ive had angels in a community tank before and the other fish bully them to death, or the angels die because the water wasnt absolutely perfect
... so this is why i wanna start a new tank just for angels soo i can give them the best posible enviroment 
any help will be much appreciated
