Cespitularia Question

[Tennyson]

Hello, I've just got a quick question, it may be dumb but I was just wondering why this little piece of cespit was looking alot nicer then the rest of the entire colony? It's polyps are much more extended and alot nicer looking and it's getting same flow, lighting etc.

Is it like that all the time? I have frags of this all really close to each other and they seem to just randomly close and open up. Two frags could be touching and one will be closed and the other flowing.

If it is consistent... what else is around the ones closed? Different corals can cause issues.

Yes its consistent. And there are no other corals so I'm not sure what it is. Theyr all healthy but mmy main colony could expand more. Could it be that the main colony is crowded?

They are moody...can die from changes or react differently.
