I got that in a discount frag tank at World Wide Corals. I believe it is a favite pentagona. They were calling it a war coral. We have 2 of them in the tank and they both grow like weeds. Very nice red and yellow encrusting type coral. Thank you
The acan died due to the growth of the llama losa chalice that blocked all the light. Haven't had any aggression issues with the war coral except it grows like a weed.
Thanks for liking the tank.
