Stubborn Aussie Acan

[j2me5ku]

I bought this "Blood Diamond" Aussie Acan about a month ago and had it in my 20G until my frag tank was set up. When I first got it, it opened up and plumped up nicely. The acan was under MH 150W 14k Phoenix on Sunpod.

When I finished my 10gal frag tank and had set it up with water, I moved it there. Ever since I moved it to the frag tank, the polyps never fully extended. All my other corals were fine. The corals in my frag tank are under a PC 80W 6500K/10K Daylight and 420nm/460nm Actinics.

After a couple days in my frag tank, and no signs of it openning up, I decided to move it back to my 20 gal display. After doing some research, and everybody's consensus that medium to high light is preferred for aussies, I thought that my 20G would be a better environment for it to recuperate.

However, it is now day 3; the acan is back in it's original environment and no signs of polyp extension. What is wrong with my acan? Why the sudden attitude?

Any help would be great

Thanks

20G Param:
No3 - ~0ppm
Ammonia - 0ppm
pH - 8.1
Ca - ~470
Alk - 2.5 meq/L

10G Param:
No3 - ~0ppm

(When my last water change on my 20G, the water was used to jump start the frag tank)

Maybe it's stressed from being moved between tanks, especially acclimating to the different lighting. I'd pick one tank and try leaving it there for a while to see if it improves.

yea im gonna leave it in my 20gal permanently, until it needs fraggin. but i have never seen a coral take this long to get acclimated. as soon as i brought it home from the store, an hour later, the polyps extended. i'll give it a bit more time.

I have found that these aussie acans dont like to be moved to much.

Is it just me or this is painfully obvious?

The coral is new and getting use to your 20 display, then moved it into an unestablished system (need more info on this as well, whats the filtration/LR,sump, fuge?, etc) . Then move it back to the 20 to get use to again. To see a coral take more than 3 days is not at all uncommon IME, and usually comes with a good explenation such as this

Stop moving it
