Interesting feedback about the Metal Halid lights as a requirement for anemones.
My favorite reef animals are anemones, any anemone - I love them. Unfortunately, people do say they are touchy to keep.
I have a LTA, BTA, Condy, Saeba and they are under a Coralife Aqualight lunar light system, 196 wats in a 50 gallon tank. I judge needs of my animals based on how they look and what I read.
For the animals that live in the center of the tank, they are doing well and have not moved from their spot. They are thriving, rich color and are happy.
However, some of the inhabitants that are near the outer sides of the tank are not getting enough light and I order another 96 watt strip light to provide more light coverage.
I haven't heard before that metal halide is required for anemones, however they are for some animals such as clams and others.
I think if you can get between the 5-6 watts per gallon, your ok.
Watch how your animals are acting and see if they move. I know from my experience that most of my anemones do not like a lot of current, they like some movement, but not super strong.
I would agree that saeba's are one of the more delicate anemones, I have never seen one in a lfs that was larger than a 1/2 dollar at best, not sure why and they are always pure white. I think they are stressed out and either removed to soon or maybe they shoudln't be kept at all.
My BTA is doing extreemly well, is healthy. Deflates and inflates daily, has grown and eats regularly. He is also about 10 inches away from the top surface of the tank and in the center so he is getting most of the light. I will be taking better care of my guys that are not as close to the center with the second light strip I will be getting.
So far, I haven't seen the need for metal halid lights in my tank. I might be ok because I do have alot of rock in there and animals are raised about 5 inches and in some places more, from the floor.
