Although my trouble was not with Flame Angels it was very similar with first a Raccoon Butterfly and then a Small Blueface Angelfish. In the last couple months in my QT I have introduced a very small Yellow Tang and a Raccoon Butterfly. Both where eating, the Raccoon was very friendly coming up to the glass to be fed. 15 days into QT I found him dead. Next up was the angel, eating like a pig but around 15 days found dead. There was no aggression, and the tang was quite a bit smaller than both. All three fish came from Quality Marine which I consider a good wholesaler but not sure why I am having issues recently. I really do not want to tie the negative responses I have seen here on RC to issue with LA but I feel there is a problem with some QM fish. The YT is still doing fine
