Fiji Fox Face and Magnificent Fox Face
 

Hi Guys,

Can I keep Fiji Fox Face and Magnificent Fox Face together in a my 220 gal tank or will they fight?

I seen a tank somewhere that had 5 species and they got along, but I also seen a tank that had two that fought, add them at the same time if you go for it. You're taking a chance if you do.

I have a one spot yellow fox face and an orange spotted rabbit fish in a 230g that (to my surprise) get along fine.

you'll be fine. just a few question to narrow your question down.
are they the same size?
are you putting them both in at the same time?

I have a 6 inch foxface and added a 2 inch magificant. They swim together like they have always been together
