Well it's definitely dieing from the inside.. crazy amount of guts being spewed out and cloudy expell, (nothing since after wc though) we'll see if it can stop that process.
I wonder the same ..I know a fellow hobbyist that does NOT treat nems..He puts them in a holding tank with an algae scrubber that utilizes a dump bucket..The nems get strong water surges every time the dump bucket drops , and he does many large water changes over the 1st few days of treatment.. W/C's helps them purge ? Clean oxygenated water from the scrubber helps them clear up infection ? All things I wonder about ...
I think this could definitely help, as it does help to remove the pathogen but allows the anemone to completely purge its system periodically. It's basically the same process as Cipro QT, but without the Cipro. I firmly believe that the pathogen is directly tied to the zooxanthellae, since all infected anemones expel dead zoox. They have to be able to expel the pathogen without taking any back in, so clean water is essential. This is also why they do the deflate/inflate process over and over. We NEVER see this with healthy gigantea.
This sounds like Haddonis over here. The only gigs I lost are ones that are already doing poorly and I get at a discount (2 out of 10) and the mags are super healthy (0 for 4), but I lost 50% of the Haddonis (5 out of 10) I've gotten because they're from Indonesia rather than locally from Okinawa (And they don't tolerate antibiotics nearly as well as gigs/mags IME).I completely agree with all of this.
Specifically regarding gigantea, I can't stress how important it is to NOT add it to the DT right away, no matter how good it looks. They can take up to a month to show symptoms. They also don't respond to high levels of phosphate, so it water quality isn't pristine, this could exasperate the problem. Once it deflates even ONCE, you must absolutely start treatment.
This is why I always use fresh salt water when QTing anemones -- never tank water -- since it eliminates any possibility of irritants (bacteria, chemicals already present such as lanthanum chloride, pathogens such as ich, etc.).
Regarding use of Cipro, there's no correct answer. I've been researching the supply chain for gigantea for years, trying to pinpoint collectors, exporters, and importers, and there are too many entry points and each has their own protocol. I've heard that some exporters blanket treat their anemones with Cipro but the protocal isn't thorough, so it may do more harm than good. Ideally you want the shortest supply chain possible, so that we can treat the anemones on our own. If you can find a LFS that imports direct, that's the best option.
Regarding water volume, I do think doubling for larger specimens should help. What's that saying? "Dilution is the solution to pollution"
Since the price of gigantea has increased significantly, I haven't been tempted to buy one. In the past couple of years, I've only treated a blue one for a friend. I was able to successfully treat it with Cipro, but he managed to kill it. I've had much better luck with magnifica. Some I didn't need to treat.
Any chance you’d be willing to share your research?
No pressure, y’all have already shared a vast wealth of info.
Hah! I'm not planning to write a research paper, if that's what you're looking for.Any chance you’d be willing to share your research?
OP- so sorry for your loss.
+1 to some kind of allelopathy occurring among carpets in general. I run an oversized carbon reactor and ozone which seems to do the trick, but it’s visually apparent when it’s time to change the carbon in the smaller system I have that doesn’t use ozone - the anemones start to look less happy.Hah! I'm not planning to write a research paper, if that's what you're looking for.
I probably shouldn't have used the word "research" as that implies something a bit more formal then what I've been doing. Where should I start?
I've always been fascinated with gigantea, probably going on 20 years now. I had a tan one that I acquired from a local reefer over 10 years ago. This was prior to OrionN developing his protocol for treating anemones with antibiotics. At the time, there were only about a dozen or so people that I knew of in the US who had gigantea anemones. One person was somewhat local to me, and she had several in her collection, and we eventually became friends. We frequently messaged each other (her screen name was shutiny on Reef Central "RC") and she provided me with a ton of helpful information regarding care, reproduction, and availability of specimens via LFS and her other sources. Unfortunately, she ended up taking down her tanks and sold her entire collection of anemones, which was quite extensive. Two of her gigantea--a green and purple--are on display at the CA Academy of Sciences. I'll share a video if I can find it.
It's worth noting that prior to OrionN's protocol, gigs were being imported on a somewhat regular basis, though seasonal here in the U.S. Almost all of them died, despite everyone's best efforts to save them. By almost all, I mean ~99% failure rate. It was relatively easy to track, because at the time, RC had a lot a active members in the anemone forum, and many members posted when they acquired a gigantea, and no one knew how to save them. At the same time, I started tracking where the gigs were coming from -- from LFS or online retailer, and if I could find out if it was via exporter or wholesaler.
Once OrionN's protocol caught on, we saw a notable uptick in the survival rate. There was still a high failure rate, but the results were better than the 99% failure rate I previously described, so we were still making progress. The unknowns are still the same as they were then: we assume it's an infection, but we don't know for sure what it infects (though as I've mentioned in the past, I'm convinced the pathogen infects the zoox and not the anemone directly), what the tipping point is (where the gig recovers or it ends of dying), and what other antibiotics can be used (Cipro by far has been proven to be the most effective, though some have had success with Septra and Chemipure, which has erythromycin as its active ingredient). Results are mixed because infected gigs were treated at different times -- some were prophylactically treated and others began treatment when in terrible condition.
Over the course of ten years, I've treated around 40+ gigantea--with unfortunately--a low rate of success. At one point, I was purchasing any gig I could find, not matter the condition both via LFS and online (tan gigs were only $40 at one point and if I bought multiple specimens I'd qualify for free shipping). I slowly began to be able to assess the overall condition of a gig, and didn't purchase any I deemed not treatable. Each treatment taught me something new, which is why my protocol now includes two tanks with identical equipment--one thoroughly dries overnight while the other in use--which helps to ensure that as much of the pathogen is removed with each water change as possible. Now that my friends have gigs, and the rate of success is higher, I've stopped buying and treating them. At one point, I had 9 gigs, but have dropped my collection down to four, though I am looking for a green one to replace the one I lost a couple of years ago. I compared notes with other gig owners who have multiple specimens in the same tank, and many of us have experienced the same thing: one gig becomes dominant, while the others slowly get smaller in size and if not dealt with--either by moving to another tank or running a ton of carbon or doing frequent water changes--they slowly wither away. I simply don't have a system large enough to successfully keep multiple gigs long term.
I also found quite a few formal studies done on S. gigantea, but most were focused on neurotoxins. One that I found interesting, not due to subject matter, but rather that it mentions that people eat gigs, is this one. Unfortunately, many of the articles that I bookmarked are now behind paywalls.
There are also a lot of tidbits of information that I've gathered along the way. For example, a friend of mine who used to own a LFS and then transitioned to become an exporter told me that gigs are common, more common than haddoni, which isn't evident since we see a lot more haddoni than we do gigantea (here in the U.S.). One hobbyist was lucky enough to have his gigantea spawn, and he found what he thought were baby gigantea (and many of us concurred), but he was never able to grow them. There was a time when we saw quite a few gigantea enter the supply chain that were cut, or showed signed of being cut, but only a few survived long term. I still believe that it's not possible to force propagate them, but I know one person (who shall remain nameless because he is active on R2R) who has experimented with it.
