Anemone's can die from bad water conditions, over stressed condition such as lack of food and poor lighting or bad quality of water.
Personally I have not lost a rose to any of the above, only to Power heads and filter intakes, but that was in my early years of owning them.
I feed them every 3 days ( babies that are under 3 inches that is) and the larger ones are fed once a week.
I have never had a rose die from splitting either as I keep the water pristine with water changes.
I have all live rock and live sand to help keep it as clean as possible, a huge clean up crew and plenty of pods to keep it all cleaned up.
Loads of snails, some queen conchs, Medusa worms, Bristleworms ,red crabs and large green brittle stars,and a lot of other funny looking critters come alive at night.
Personally I think it’s the building block of a healthy tank . A large clean up crew that will eat all of the waste and excess food, thus keeping the tank sparkling clean and clear.
I have no algae at all on the glass in my large rose tank because of the clean up crew. I do however get a white film on the glass and I use the floating Mag Float on it every 2 or 3 days. I never disturb my tank, all rock and Caulerpa that I keep in the tank is left undisturbed. Caulerpa is kept in check by the yellow tang somewhat but I do thin it on occasion. It helps to keep the water clear and adds a natural appearance to the tank. (just my opinion again).
Also I sell what I harvest so if you are looking for some, check the "For Sale " section.
