SPS behavior

[duke62]

I have 2 pieces of SPS that are doing something odd. They are creating a paddle at the ends of one of there stems to keep the flow from hitting them directly. Has anyone elses SPS done this. One is a hairy acro and the other is my pink lemonade

Yes, my acropora would grow into the flow with the branches being much wider on the flow side. I'll post pics if you want later.
