Will these pair up?

[causeofhim]

Black & white false percula pair up with an orange & white false perc?

 

[sdunkin]

Yes, they are just variants of the same species.

 

[tcmfish]

You could ever pair it with a perc, but I don't recommend that.

And will they host in my RBTA?

 

[$eaba$$]

depends. sometimes yes and sometimes no. most likely yes in time, but you never know. you will just have to wait and see
