Aiptasia anemones are indeed photosynthetic, ie zooxanthellates. Just look at their nice brown color, they are full of symbiots. However, they have the ability to survive without lighting. They can instead survive solely on eating. This is why depriving them of light is not a method to kill them. In fact, light deprivation often causes them to expel gametes and reproduce. So, not a good idea if you want to get rid of them.
