Pairing Dottyback

[Newbie1215]

Good Morning Fellas. Just out of Curiosity, can you pair a purple stripe dotty to a magenta dotty? Or are they able to paired up to any other dotty family? I have a purple stipe dotty in my 30g tank setup with 2 ocellaries clowns, some crabs and snails and I wonder if I can purchase a 10g tank for possible dotty pairing.

Thanks,
Z
