New gem tang addition question...

[gsiegel]

Adding a 7 inch gem tang to a 300g tank with other tangs including a
Desjardins 9 in (has not been aggressive with other fish yet)
Naso 8 in (stereotypical docile fish)
Blue hippo 8 in (can be a bit moody)
Purple 5 in but was able to put him in the refugium while the gem arrives and acclimates

Also have a pair of bellus angels (the male can be tempermental on occasion)
Spotted rabbit - very docile

With adding the gem am I better off adding another tang with him?? Thought of an orange shoulder but concerned with the blue hippo.
I can add a yellow but could be asking for problems with the purple even after being in a time out (he has been in the tank for 3+ years)
Suggestions to assure the gem has the easiest transition possible??

Easiest transition possible...take out the sail fin, blue, and purple for a week and let the gem get established. If that’s not possible then catch the purple and watch the des go nuts on the gem and catch the des out at that point.

Using a box helps of course but I would try catching the others first

buy an acclimation box... It could help
