Bam !!!! I knew I would lure you out Peter E. I had several myths I wanted to share and this is one of them. I shake my head when I hear the adamant responses of this particular polyps grows very slow and that is why it is so expensive. People, IT AIN'T TRUE. Why so cocky Mooch ? Not cocky at all on the contrary. If we spent as much time talking about reef and tank diversity, half of the issues we experienced here would be put to rest. Now I hate names and I hate to use them, so I won't, LOL, GOTCHA, but this purple paly which everyone says grow very slow is pure Oscar Mayer Bologna. The polyp grows slower for one reefer and faster for another for one reason and one reason alone, tank parameter, environment including lighting, just as Peter said. I had them and they grew like crazy. My buddy Jim who sold an entire large colony of them grew them for years and sold them to everybody here in Michigan. Some polyps prefer less light depending on the region of origin, others prefer more intense lighting. Many confuse light adaptability to light necessity. If one is experiencing slow group, one needs to do nothing more than to research where the polyp was collected and make marginal changes and document those changes to see the growth that is desired.
