Don't know the difference between tank raised & wild caught (tank raised weren't available the last time I had one).
I can tell you that they love
Open Brain corals, and will usually nip at these over everything else. The Flames I have had in the past have also nipped at Xenia & Colt corals, and a Bubble Coral.
I've had a Flame that nipped at corals since first being put into the tank, and another that didn't touch a coral until having been in the tank for almost a year. IME
, eventually, they will all begin to nip at LPS
Just my experience....
