Ummm...I never said anything about this being documented. Based on the link in the original post, I am and so are others applauding the efforts of Ana.

but no pictures of those just the aiptasia so makes me wonder if the names of the other 2 were just given or are there actual nems and do they have any spawning going on.
Im not convinced until we see pictures of bta/crispas captive raised and living.

Working on it
If she has fully raised this species, I would be interested in techniques she used to raise them. It wouldn't be incredibly difficult to raise them (at least extrapolating to other species).
fwiw: the inset picture on this page appears to be a very small E. quadricolor. But then mine look like that when they go through the overflow teeth, intake strainers, etc.

After receiving an email from Cindy Lebsack telling me about this thread and the interest in my research I thought I should respond. My work documents the sexual reproduction, larval development, settlement and metamorphosis of two host sea anemone species, Entacmaea quadricolor and Heteractis crispa. Predictable spawning periods have been observed during the past three years of research, with male and female anemones releasing sperm and eggs into the water column, where external fertilisation and development into small swimming larvae takes place. After three to five days in the water column, these larvae begin to settle on the substratum where they grow into juvenile anemones. In both species, zooxanthellae are acquired via materal inheritance and therefore the spawned eggs already have zooxanthellae. Juvenile H. crispa anemones have been successfully raised in aquaria, and are now over 2 years old. The anemones shown in the photograph are actually H. crispa juveniles (not Aptasia), and they now have an oral disc diameter of up to ~10 cm.

Hi, Anna- welcome to RC.
I'm interested in knowing what you might patent in regards to raising captive anemones....

The Solitary Islands has two species of host sea anemone, E. quadricolor and H. cripsa. I would love to expand my research to include other species of anemone, that would obviously mean travelling to other locations in the Indo-Pacific (which wouldn't be a bad thing! 
). At the moment I am finishing off the final stages of my PhD write up, after that I will try and look for funding to support such research.
The patent covers the methods that were developed to in order to determine spawning times and the techniques used to sucessfully raise and settle the juvenile anemones.

Humorous to watch all of you who Just got done Discrediting and Slamming this person extend the "Welcome to RC"...I think ill use this approach in the Future at my Store.. After someone comes in,and ive completely Offended and Insulted them..Ill try the old "Welcome to my Store"...And see how much they appreciate my Hospitality...From what i have noticed from the short time ive been here... More RC users should try and get ALL the facts before they start with thier PERSONAL opinions....JMO...

I guess I am glad that I started this thread after all. At first I thought people were going to laugh at me and it was going to be erased but now I am actually interested in seeing where this thread goes. I have been interested in the subject for a couple months now. I hope that I can someday breed and raise them. Anyways, I am very glad to hear this kind of research is going on.
Anna, While studying anemones in your Doctoral studies do you agree with what many people have speculated, that anemones have very long lifespans?

I think we were all just having a little fun with the idea of getting a grant or patent for having aptasia reproduce. Saying we were slamming or discrediting is a bit of a stretch and all kidding aside I can't imagine any of us who wouldn't be behind this research %100.
Anyway, Anna, here are a couple of other threads you might be interested in

Based on the juvenile growth rates that I have observed I would agree with the speculation that they may be very long lived, however as these juveniles have been keep in aquarium conditions with very little additional feeding further study of field populations is needed before coming to a definitative answer.
Hi Anna,
Thanks for coming to Reef Central and sharing your expertise with us.
A lot of us here are very passionate about the sea anemones and I have a lot of respect / envy for the research you are doing.
I have spent a lot of times learning about these animals and there are some photos of H. magnifica, and Stichoducyla sp. sexual and asexual reproductions in my systems.
Some of old pictures you may find them on my site www.exoticcoral.com. I have lot more pictures that are not on my site but be happy to share.
Great work you have done, Anna!
Again, thanks for chatting with us

Or maybe others shouldn't be so skeptical.
I commend your efforts Ana. Sorry about calling the picture in the link aptasia, I was caught off gaurd.
Anna,
[welcome]
If this is not patented information, have you found a way to stimulate spawning in E. quads? I have a large number of Rose BTA clones that spawned several years ago in my tank (that's how I learned they were female ). I have since aquired a male RBTA for the tank, but have not had any spawning activity since (naturally 
).
Any suggestions?
Thank you.
Kevin

no wonder its called the clown(fish) forum.anyways im a bit more curious on what the settlement substrate is for these two species and what would the larvea and grow out systems for them be like?
ive done some work on the correlation between light levels and food(caloric) needs on condalactis anemones, and what nutrients anemones need, might be of some interest to you?!
TIA
