So, I've tried 2 giganteas in the past, probably over 10 years ago, without success. I've done well with ritteris and have been on the hunt for a nice gigantea for over a year.
I think I may have struck gold. This was held at the vendor's for 2 months and was shipped via fedex. It arrived a couple hours late and looked like this in the bag:
Water looked a little cloudy so I did an abbreviated acclimation (about 20 minute drip after emptying out some of the original water). Discussed this with the vendor, who also agreed.
The anemone was a little sticky when I went into the bag, which was encouraging. It also immediately attached. The mouth gaped slightly but the tentacles are long and wavy and on day two, the mouth is tight and the anemone is starting to hold itself up well. I removed my ritteri and the female clown went into the gigantea almost immediately. She went to the male and kept trying to coax him over and today, they are both in the gigantea.
The anemone exhibits all the positive signs: tight mouth, long wavy tentacles, holds itself up, no inflation deflation cycles. It's sitting about 24" under a powermodule with some newspaper interposed to cut out the light. It sits on a large flat rock with a small depression centrally, though it's currently a little off to the side. I took this video under just the dawn/dusk bulbs and have cut the main lights down to 5 hours for now to avoid stressing it due to transport.
less then 24 hours after acclimation:

Any other hints/suggestions?
