Hi Gary,
That looks like a H. crispa to me. The tentacles are too long and thin for a malu.
In addition the column is white and seems leathery to me as opposed to the tan/delicate column that malu is supposed to have.
I just looked at that thread for the first time just before I read your message. I didn't read it all the way through, but you guys seem to giving him good advice.
