umbrella Xenia
 

I have a book that says that Umbrella Xenia is best not keep with stony corals or Flame Angelfish. Does anyone know if this is true or why they can’t be kept together?

There's lots of references that one should have separate displays for soft, SPS and LPS and ideally for each species due long term effects of allelopathy in the confines of a reef tank but pictures seem otherwise. Now if one was to cram a bunch of different corals in a tiny tank with no water changes or skimming...

As never had an angelfish, can't comment.
