What kind of bulb is a 40W PC? Is it meant for a 55G tank? Let's be reasonable...when I say this, it obviously means(to anyone who has ever worked in reefs, at least) that you will be using proper requirements on amount of light. I.E. if you hav a 55G, you should obviously use a 48" fixture and use at least 220W of PC. I would think that anyone caring for a reefs would understand this without someone having to explain that...I guess I was wrong. I assumed and I guess I shouldn't do that with the people on here. My bad.
That statement in your second paragraph is exactly why I said what I did. I will not recommend it because most experts will say that you should not do it. I don't want someone coming back to me and whining about me telling them something that killed some of their livestock or holding me accountable for what could be one of thousands of problems by blaming it on lighting and concluding it's my fault.
Again, that being said, I, along with many other people, have had extremely good success under any reef light; let me add, withing normal range for reef caretaking, not 10W on a 1000G tank, for those who may misread my comments. I initially began with the politically correct response and continued on to my personal experiences. I feel that my statement still holds from personal experience of at this moment doing what some experts say is impossible...I don't see how it is so impossible if so many peole do it with such great results. Then again, everything in this hobby is what works for you, not what works for other people. Find out what works for you and stick with it. Don't come here for answers, come here for experiences. Answers are only worth the tank they are working for, not for your tank.
Also, I think the conditions that raised the anemone is a bigger factor in splitting than stress. Commonly tank bred/cloned/raised anemones that come from a split are much more likely to split in your aquarium than a wild caught one. Of course, this is only from what I have read. I do not claim to be an expert, but I do read about this stuff all day. I read experiences, I experience myself, I experiment, I read breeders, aquaculturalists, their tests and findings. This is what interests me, so I don't only use RC or a few experts books. Yes, those experts know a lot about what they are talking, but the hobbiests out there that are not necessarily bio doctors still have experienced(and many times for more years than any of those young doctors) and are as knowledgable and respected as the best of them. Don't discount any knowledge because it doesn't happen in your tank. It can and probably has happened somewhere. We have to remember RC is one of the top sources for info on reef topics, but is far from the ONLY source. It just seems like most of that link is just regurgitated from the books on reference. It is a great quick source for anemones, but I wonder what actual research they did to come up with VHO being the minimum. Was it just a poll of people.
Again, I just give my experience and the stories I have been told. I will say again and for the last time, I keep these anemones, I have them under multiple lighting setups, I have them from the same DNA(splits of each other), I keep the tanks fairly controlled(no I am not perfect and not an absolute scientist on the issue) and I feed exactly the same. I have a pair of clowns in each of the tanks and only one tank in which they host in the anem. I'm not trying to persuade people to go out and minimalize for a BTA, that is exactly why I said I won't recommend. On the other hand, I will not tell people it is impossible because it is not.
