Thanks im hoping it doesnt move. Its on a perfect rock, nice size crevices to hide its foot. It is not in direct light, its more on the angle of the light so it has the option to either retract into the rock since the crevices are big enough, or move backwards into another crevice of the rock. Moving forward would put it more into light.
I am keeping the flow on the side a little lower, normally have a small head down there but i moved it up higher in the tank so nothing is giving a direct blow down there.
So far so good.
