Chalice coloring

[Dave12678]

Hey guys I this frag a few weeks ago and notice that it is growing great but the edge is looks like its loosing its color. Also I noticed the edge moves, if that makes sense. Here are some pics:

Before

Now

This frag sits under 150w MH light with pretty good flow.

To me it looks a bit darker overall in the lower pictures?? I think the tissue receeds and expands like other LPS no?? I'm getting an Alien eye chalice this weekend so I'll let you know if mine moves too.

Yep they will shrink in sometimes around the edges.

the edge of chalices when inflated expands over the skeleton so it would be normal for the edge to pull in when irritated

Yeah he is sucked in on these pics. It seems like the colors change around the edge day to day.
