I screened it with 2 layers of window screening, removed 1 layer every 4 days. It's 12" deep under the water's surface. On a rock. LED lights. From what I've read, they are kind of a combo between a gig and haddoni, kind of like a rock dwelling haddoni, actually. It seems to like gentle flow, just enough to move the tents a little, and an occasional skirt lift. This one seems to like more flow than haddoni, less than gigs. I had quite a bit of flow on it to start (not knowing), and it moved to less flow, so I cut it back a little, and it didn't move anymore. It moved maybe a couple inches from where I originally put it. When I got it a few weeks ago, it was around 5 inches. Now it's around 7. It's growing fast, or just acclimated well. I've been feeding it every day though. I placed it knowing it will reach a couple feet in diameter, so it's a matter of time before I move a clam and a few corals.
When I first acclimated it, the foot swelled up to be huge, but a few hours later, it settled. Looked funny for a while. It always had a tight mouth. I waited a couple days to try food. Took food right away the first time, day 2 I think... Right now, the foot is in a crack of a rock, and it comes out like a bubble anemone, out from a protected "hole" in a rock, only it never deflates. Same size 24/7. I've never seen it deflated. It's really pretty cool. It seems like a mix of a gig and haddoni, only easier than both. Mine came with a main mouth, and a smaller mouth. Both seem to react to food.
I'm still in the trial phase of LED, I'm not 100% sold yet. My anemone's seem to be getting alot more brown to them though. I liked when they had color, but I guess brown means healthy. I personally like color better. I'll see...
I'm not an expert at them. This is my first one. I couldn't find too much for experience/info on them myself that I found valuable, other than what's on RC from the couple that own them here. Maybe others with experience can chime in and help us both more. They seem pretty far and few between.
