I have a standard orange ocellaris in my frag tank who I never moved over to my new 110g display. He's ~2" but pretty tough, I've had him a few years.
In my display I have a slightly smaller and wimpier black domino clown that's been in there a month or so to get established.
All fish are different but is this likely to be ok if I introduce the old clown into the foreign system or do I need an acclimation box to test run? Will an acclimation box even tell me anything if the more likely aggressor is the one inside it?
I don't need them to actually pair and breed or whatever, just don't kill eachother.
