i have one that i got as a frag about a year ago. its gone from a single polyp to around 6 polyps in that time. unfortunately i dont know how to post pics but through alot of research and knowing the reliable person i got the frag from, i feel confident its an actual hillae.
also, i have a coral thats similiar to clownuts with a few differences. it is completely purple and green and lacks the white and brown streaks his coral has. also it doesnt have the same echinata appearance as his. but the thick green bands are almost spot on. ive done some asking around and have heard everything from acan ish. to a possible sub species of echinata and alot of "unknown" answers.
