Domino's tail has white on end

[carper192]

Ive had a saltwater tank for 8 yrs, upgraded to a 55 gal 4 yrs ago. Now i am upgrading to a 120. My tank is set up with some of the rock from the 55 gal. After 10 days I added 3 dominos, striped goby, blue damsel, firefish from another smaller tank and a 5 yr old clown. The dominos went after the smaller domino nipping its tail. They no longer pick but now the tip of the tail is white. I am wondering if it is tail fin rot or a fungas. I have not experienced this before with my fish in the past. Is this contagious?

It may just be fin damage, or there could be a secondary bacterial infection involved. It will not be contagious to other fish unless they also get bitten fins.
Dominos can be pretty mean, you may have to separate them at some point.
