For me, it is another green toad stool. When I got a used 6 gallon nano cube from a reefer with some rocks, a green toad stool came out of 1 of those rock and it has made the journey with me for over 5 years. It has had many frags; some went to friends other went on craigslist. None of the frags was sold on the forums cause they have minimal value to the new hype corals. I still like the way the tentacle moves until I see the Japanese toad stool! Anyway, here is a few months old picture in my old tank. I keep the toad in the back of the new tank behind the big rocks now so I can't really take a good picture of it.
