Just make sure you get a pair, meaning a male and a female that have paired off for spawning, otherwise you will have death and destruction in your tank. One way of doing this is to purchase the known pair from a reputable dealer (not a fish store chain), or you can get 3-4 juveniles, when they mature and two pair off, you rehome the rest. Good luck, I've always like angel tanks, I'm sure it will be stunning.
