So I introduced a baby Tomini tang into my tank with an established gem tang . The gem tang immediately started being very aggressive towards this Tomini (no other tangs. Just some clownfish and firefish). I tried the mirror tactic which distracted him for a few hours but he immediately went back to harassing the Tomini into a tiny cave . I've spent the last 2 days trying to catch the gem tang to put it in my sump for a bit to give my Tomini a chance to acclimate better but I've been unsuccessful. During this time however, I've noticed the Tomini becoming braver and braver, coming out of his cave any chance he got to explore the land and would retreat only when the gem tang got near. I know this question is very tough to answer but do you think it is possible the Tomini will eventually learn to stand up for himself so that both can coexist? Or am I just being naive . I am worried now because I have some anthias and a wrasse on the way that I will also need to introduce in the next week and really don't want my gem wreaking havoc .
