I've been reading a few different threads on Nano Reef and Reef Central about hybridizing palys. In these threads, hobbyist have successfully hybridized Purple Deaths with Nuclear Greens, however the OP disappeared before they shared the final outcome. The farthest one of the threads I read went was two months after the grafting/splicing of the palys, at which point they had retained color from both Purple Deaths and Nuclear Greens and had created one or two offspring which also retained color from Nuclear Greens and Purple Deaths. These threads have interested me into thinking about hybridizing zoas. I have a few large colonies that I would be willing to risk a polyp from, but before I start I want your thoughts. BAR has a large panel of people who have loads of experience and knowledge, so my question is: is there something different between zoas and palys which would allow the success of hybridizing palys and the failure of hybridizing zoas? I've noticed just by looking at all of the different zoas in my tanks that they all have different polyp structures, but there are some (like Radioactive Dragon Eyes and Eagle Eyes) that have the same polyp structure. My thinking is that the zoas/palys being hybridized have to have the same structure (like PD and NG, or Eagle Eyes and Radioactive Dragon Eyes) for the hybridization to work. What are your thoughts? If I decide to go through with the experiment I will be cutting the zoas with a scalpel (while wearing glasses and gloves) outside the tank so no toxins can be released.
