Adding another butterfly

[Lb71]

Have a CBB in a 120 gallon tank with very peaceful companions. Toying the idea to add another butterfly perhaps dot dash, Mitratus, pearl scale or black back. Any comments on chances that the CBB will live peacefully with another butterfly

I think it would be fine to add another BF from your list. The CBB I've kept have been very docile. I'd try getting a new one that is a different size, either larger or smaller to lessen the chance of aggression.

It should be fine.
