Oh then your good...I though you had this shipped to you...sometimes they are dyed...
It's a very pretty color morph...I'd rather have that than my plain rbta's...
That is a rbta. Some call those 'rainbow btas.' Dyed anemones are rare and e. Quadricolor don't seem to be targets like other species. Also, 'settling in' has nothing to do with keeping the colors from changing. Sometimes the colors will change due to different lighting or overall environment.
