Adding Bangaii Cardinals

[bigsteam]

I have a 2 year old 150 gal tall reef tank with mostly soft corals and the following fish:
Yellow tang
Percula clown
Lawnmower blennie
Pseudochromis
I am thinking about adding some additional fish particularly a Bangaii Cardinal. Some of my research says since Cardinals like to school, you should add them in groups of three. Any comments?

Yes if you do get Banner Cardinal(Bangaii Cardinalfish) you should add them in atleast 3 in a group. But the the better.

They school as juveniles for protection. When they mature sexually, they will pair off. Adding three, IMO, is a gamble as you may likely end up with an "odd man out", and this third wheel may even be killed. Are you looking to have a m/f pair? If so, add a group of them (5-6) and see who pairs up. Remove the rest once a pair has been established.

i got lucky and added 2 which just so happened to be male and female. maybe they do the same thing as clowns where in a single --- environment one changes to the opposite ---. anyways mine are makin babies all the time.
