Me? I have a yellow/green gigantea that I bought from a local reefer early last fall, and I bought a blue one from Liveaquaria that arrived Saturday, but you may be thinking of someone else. Here's a picture of my green one:
Some advanced S. gigantea questions

Great discussion, folks.
As a follow up to the color question, anyone know (or have an opinion) whether the chromophores used to develop colors in giganteas have any specific dietary basis?
That is, needing a starting chromophore compound from foods it consumes that it then uses to make its own chromophores?
Protein. The green color you see in your gigantea is produced by GFP (green florescent protein) Where the anemone gets the protein for these pigments may be arguable. Maybe they build these proteins with the amino acids provided by their zooxanthellae. I'm not sure this is the case, because anemones that are totally bleached (void of zooxanthellae) will often increase their GFP if conditions are favorable. Maybe they get the protein, or amino acids, from the food they eat. Maybe, in a healthy individual, it's a combination of the two.
We know that light plays a vital role in the development of GFP and similar pigments. When I'm trying to increase these pigments, I slowly expose the animal to greater PAR. I also feed heavily. At times I'll soak the food in vitamins and amino acids, or even dose them to the tank. When feeding heavy, and/or providing extra nutrients, we have to be extra diligent about removing these nutrients. When nutrients, like phosphate, become more abundant, the zooxanthellae flourish and their brown color can overwhelm the GFP. Giving us an animal that's more brown than green.
The last half of this article my help.

I meant the yellow and green one. I was eyeballing that ad when you got it.
Did you get the blue from the divers den?

Thanks.
Are you attributing all of the different color morphs of giganteas (blue, purple, green, etc) to variations of a basic GFP structure?

Ah, OK, I understand.
Yes, here's the sales photo of the blue one from DD:
So far so good with it.

Ahh, so you are the one that bought the blue gig from dd last week
....how did it look when it arrived?

I'm not saying they are one in the same. Just closely related.
See the first four lines of the abstract in this link.

Excellent article, thanks.

I've not seen any good free online articles summarizing current research in anemone reproduction and biology. Sorry. A good textbook on invertebrate biology might be a good place to start. Ron Shimek has pay per article (or sets of articles) that he sells from his web site, and at least one relates to anemone biology.
I know no one has reported successful sexual reproduction of giganteas in an aquarium system, but does anyone know if anyone has reported spawning events with appropriate sexes that did not successfully result in any babies? Or are there just so few cases of spawning events with multiple giganteas in a single tank that there is hardly any or no data available?

I don't think you will find the info you're looking for. Healthy giganteas are still rare in the hobby. The number of tanks with two healthy giganteas is even more rare. To have two gigantea, in the same system, and healthy enough to reproduce, would be practically unheard of. At least I've never heard of it. You could be the first to change all this though.:thumbsup:
IMHO, there's a big difference between keeping one of these animals alive and seemingly healthy, and getting them into spawning condition. I view this like clownfish. Many people keep clowns for years and they never spawn. They seem outwardly healthy though. Breeders have found that an abundant, very nutritious, diet is key to getting these animals to spawn. I believe it's the same for anemones. When my female haddoni spawned, she released tens of thousands of eggs. (no exaggeration at all) That's a huge expenditure of nutrients and energy. I don't believe that the feeding schedule of most hobbyists would supply the resources needed to produce such a spawn. I've had my haddoni for quite a few years, and she never spawned. I fed her like most. When ever I was in the mood. About six months prior to the spawning, I began feeding her every day. I don't believe it's a coincidence that she spawned when she did.
Haddoni's are far more abundant in the hobby. A couple of weeks ago, when my female spawned, I searched for evidence of other females spawning in captivity, and couldn't find any. If I can't find evidence of a female haddoni spawning in captivity, I'm sure you will have a very hard time finding evidence of a female gigantea spawning.

Great, thanks for the info.
That's my dream, dozens of green and blue gigantea babies coating the sides of my system.

I have heard evidence that both gigantea and haddoni brood their young inside their bodies or at least that is an option. I have read several cases where people have purchased carpets that have release fully formed babies into the their tanks.
I am pretty sure Shutiny reported that happening.
