Okay, I bought mine MO from Reef Science (now out of business) in March 1996. Paid $39.95 for it. It is a bright green Hydnophora the glows under actinics. It is smooth unlike most Hydnophoras that you see for sale. I have never seen another like it. It has grown under VHOs, PC and combo of MH and PCs. Here is a picture which does not do it justice.
