3 male Banggai in a 150G ?

[Guillaume]

Hi all,

I've been trying to identify sex in LFS with the vent method (http://www.advancedaquarist.com/blog/how-to-determine-the-sex-of-banggai-cardinalfish) but was unable to do it at the LFS. My goal was to buy one male and one female.
I ended up buying seperatly 3 cardinals and being able to sex them at home only. I have 3 male finaly.

Will they get along ok in my 150G without killing themself?

Roomates:
-one zebrasoma flavescent
-Two perculas
-One Valenciennea puellaris
-12 Chromis (to come)
- Low-medium load of corals

General view. There are some caves to hide which you don't see here.

Chances are two will die from aggression.

Only a m/f pair will work long term with no other bangaii cardinals, IMO.

That is what I was fearing: no possibility of male living togheter, even without female to compete for.
Damn sexing, it is so hard to do at the LFS.
