adding group of bangaii cardinals

[akhanf]

I already have one bangaii cardinal in my 55 (been there about 6 months). Do you think it's ok to add 3 more to make a group of 4? I heard they can get aggressive with each other, is this true? I also have an established potters angel, is there a chance he'll be aggressive to the newcomers?

Thanks for your help!

Banggai cardinals are not nearly as agreeable with one another as many of their cousins (namely pajama cardinals).

As soon as a pair develops among the Bangaii cardinals, they will kill off any other Bangaiis in the aquarium.

So I guess I could either add just one and hope they pair up, or not add anymore..

Thanks!
