Timfish Posted April 2, 2014 Share Posted April 2, 2014 Was drinking my coffee and noticed something was screwy with my tank Took a closer look and there were just a dozen or so bright orange eggs floating around . D^%^! I missed my Yellow Stone Polyps breeding again! Been trying to catch them at it again for several years now . Here's the link to my first post: http://www.austinreefclub.com/topic/12279-polyp-porn/?hl=%2Bpolyp+%2Bporn For those interested they seem to prefer to do it several hours before the lights come on irregardless of when the lights come on. Of the several occasions I've found eggs floating around in the tank 3 or 4 were an hour or two before lights came on and once was just before lights went off. The only time I was actually able to catch them in the act was 3 hours before lights came on. The pictures in the above post is from the only occasion I actually observed them laying eggs. These are all the same clone line so I have no idea if they are capable of actually developing even if they are releasing sperm as well as eggs (SECORE has shown Acropora palmeta cannot self fertilize). There also does not seem to be any correlation to the phases of the moon and as pointed out, time of day. (I wonder if theyr'e waiting until I'm not around! ) 2 Quote Link to comment Share on other sites More sharing options...
Wade Posted April 2, 2014 Share Posted April 2, 2014 Now I know how they propagate. Never really thought about it before. Someone asked me a while back if they reproduce like other animals, but I never took the time to Google it. Cool. Quote Link to comment Share on other sites More sharing options...
FarmerTy Posted April 2, 2014 Share Posted April 2, 2014 In a tank setting, I would say it is more the exception than the norm that corals will reproduce via sexual reproduction. Most of our frags that get sold on the forums are through asexual budding/fragmentation. Quote Link to comment Share on other sites More sharing options...

(I wonder if theyr'e waiting until I'm not around! ) maybe they like a little privacy. not everyone wants to be watched in their intimate moments.

Timfish Posted April 2, 2014 Author Share Posted April 2, 2014 Successful sexual propagation in reef aquaria is going to be extremely rare and like JeeperTy pointed out asexual propagation by budding, splitting or fragmentation is the way it's going to happen. Considering what little research that is available indicates the species that are true hermaphrodites cannot self fertilize and there is no practical way for any of us to verify we have two different clones lines it strikes me as being very, very unlikely to happen. These Yellow Stone Polyps being a case in point. all that I have have in my various tanks came from one wild colony about 15 years ago so all are of the same clone line. Many have been given away or sold over the years so even if I tried getting some more in an attempt to have them successfully reproduce sexually and I got some from another local source I may end up with the same clone line which wouldn't work.
