Anthelia on the Move

[debincalif]

I started with one lone polyp of anthelia, and it has now grown to 8 polyps over 2 months. I'm curious, though, why it is moving across the rock. All of the polyps are creeping toward the back/side of the tank. Is this normal?

Is the flow directing them that way?

Now that I look at it more, yeah, the flow is going that direction. Makes sense now. Thanks!
