Treadfin Butterfly

[brendac]

I need to know can I put a treadfin butterfly in with a golden stripe maroon..a karen angel..a flame angel and a yellow tang?? I heard that the treadfin is a hardly butterfly is this true? My tank is 125g I had bought a small threadfin about 3 weeks ago and within 1 week it was dead..I tried to find it but as strange as it may sound it was no place in sight

Were the other fish aggressive to the one you placed in there already ??????
BTW, the Threadfin is generaly hardy as far as Butterflies go....
