My Urchin keeps irritating my anemone!

[...]

Sorry for posting a lot, anyway, my anemone moved last night (Of course when I left the wave pump on) and I do not know if this was my pincushion urchin because this urchin as kept bothering him since we got them, he would also topple the rock and his spikes would always push the anemone, anyway, I saw that the anemone moved to a different rock and my urchin was on his old rock, is the urchin irritating the BTA?

Difficult to judge - you have to observe by yourself if this is what´s happen.
