Green button polyp - inverted?

[bdturtle21]

I have a green button polyp that has been acting strange the past 2-3 weeks. It opens up, but pulls its "bell" down over itself so it is more or less inverted. See pic below (not great resolution, sorry!). In the past, this button polyp has been wide open and very happy. Not sure what's going on...??

The other coral inhabitants in my tank are doing great. I have a hammer, duncan, candy cane, and small brain as well as several other zoas and a mushroom. Fish are all happy too.

Tank specs: 55 gallon bow front, 15 gallon sump/fuge, 50lbs live sand, ~50lbs live rock. I moved the tank about 2 months ago (short move) and everything has settled in well to the new home.
Salinity 1.023
pH - 8.5
Alk - 7.0 dkh (2.5 Meg/L)
Nitrate - 7ppm
Nitrite - 0
Ammonia - 0
Phos - 0
Ca - 380-400

I did purchase a new light (Hydra52 HD), and spend 2 months slowly ramping up - actually am still ramping up (only at 50% max) - I think this light at full capacity would be too strong for my small tank.

Anyhow, if anyone has any thoughts on what's going on w/ my green button polyp I would greatly appreciate it.

Thanks!

Anyone....?

That is strange, but I'm not sure I'd worry about it. Those kinds of palys are almost impossible to kill.

its expanding/growing.it will shoot strings of flesh on the rock and smaller ones will pop up from it.

Hrm, it doesn't look like it is expanding/growing... it looks rather unhappy.

I'm sure it will be fine - I'm just curious what's going on with it... If it does grow/expand like you say I'll let you know!

Thanks!

They are fine, my Grandis do that from time to time. What you don't want to see is them staying closed or their fingers gone, that's usually an indication that something in the water isn't to their liking in the water.

Mine recently did that in my tank here at work. In my case, it was too much light. I moved them out of the LED blast and after a couple days they flipped right back to normal.
