Tang Trouble

[Donnie2112]

I guess this is a war story more then a question, I decided to try adding a small powder blue tang to my tank which was previously stocked with just 5 chromis and a 3 1/2 to 4 inch yellow tang. Any way my yellow tang flared up and went to town chasing and trying to beat the tar out of the poor powder blue. So I quickly netted the powder blue and moved him down to my sump. I am planning on taking the powder blue back to the store tomorrow. The only thing I guess I'd like to know is if there's any reason the little guy shouldn't be in the sump for tonight and most of tomorrow? Also is there anything that is worth trying to try to get them to get along? Even if there is a way I don't think I want to risk it. I feel like a dummy for risking it, I had read and seen a lot of tanks that mixed those two species and thought it should be ok. Bummer deal.
