I have mainly branching euphyllia , never had much joy from walling or torches , probably because they have been damaged in transportation to the shops. Over the 14 years I have had kh from 5.6 to 14.8 , temperature from 24 to 32 degrees c , magnesium at differing levels and the one thing that has stayed stable is an alternating random flow , not too heavy and I dose lots of iodine, and I mean a lot.
The big frogspawn has grown from a one head frag 14 years ago and has been fragged when I moved tanks ( it was too big to get out in one piece )
The monti and sps have been removed recently and within 2 months the euphyllia have expanded to fill the space left. Maybe I'm just lucky with them . I even had one with brown jelly disease that I treated the one head and it survived. ( so those that say they don't survive , they can )
