yellow tang & copperband

[Kigs]

I introduced a copperband butterfly to my 75g. Only inhabitant is a yellow tang, and he's been chasing the copperband around, and brushing against it. Should I remove it? Or is this a normal introductory behavior?

its perfectly normal for a yellow tang to behave agressively to new tankmates. it should stop soon. However in the future it would be best to add agressive fish last.

I will keep that in mind. I never expected the yellow tang to be the "aggressor"
