It actually takes quite a while for the Berghias to get going on the aptasia. Most people don't notice anything for at least the first month. The usually think the Nudis are dead. Unfortunately a lot of the times people end up trying something else in that amount of time like getting rid of the rock or putting something else in the tank to eat the aptasia. They don't get a chance to see how well they work.
