Happy, Detached, Reattached, Half Happy?

[Akimbo]

When I upgraded tanks my Metallic Green Mushroom detached between the tanks. I spent two weeks getting it to reattach to a new one rock. Before it detached it was very happy. Opening up to roughing the diameter of the bottom of a glass Coke bottle. Now that it is reattached and in my new tank it is only opening up to maybe the size of a penny. I've tried many different levels of flow and lighting over the past few months and nothing seems to phase it except no direct light which caused it to not open at all.

Any recommendations?

Is the lighting different?

Worse case scenario:

Its a shroom...it will open up if you are patient enough. Are there any other corals in their?

Yeah lighting is a lot different. I went from a 10g cheap hood with those little PC bulbs you can get at Petco to a 48" Corallife 53008

How long ago was the upgrade? Its prob a lighting issue but I would MAKE sure all of your water parameters are correct.

It was about 2 months ago now. Its only that one shroom that I have issues with...all my other corals are doing excellent. Including my Candy Cane that is splitting for the second time in a month
