Why have I not looked into this leather before?
The Pink Nepthea? Difficult to say but I do know it was brought to attention, or maybe became more popular, by Koji Wada and the hobbyist in Japan. It also has a bit of mystic or allure similar to the ORA Pearlberry. At times one will say hey, look at my Koji Wada Pink Nepthea and hobbyist say no, no go. Or others will ask if this Pink Nepthea is a Koji Wada. Sort of funny - no disrespect.
I had a frag of it a few years back and it grew super quick. It started off slow but once I got the frag placed such that it had stronger water movement it took off like bamboo . I lost mine and never found out the root cause as it was sudden. I am starting to believe that it was carbon and gfo related and maybe my error in not rinsing it as well as I thought.
I will say that if you have a LFS or fellow hobbyist near you that carries it, worth your time to see in person. Electronic media / format does not do it justice. You really need to see the crisp colors in person preferably under natural lighting, not heavy windex blue. A healthy coral will have noticeable polyp extension.
It is truly is an underrated coral. If being honest is a good thing. Not pushing a vendor but Marine Farmers will offer frags. A bit of a premium but a good source never the less that also supports a small family business.
