Yes, indeed, Giant but exoctically colorful feather duster is exactly what I called them. I found them to be less demanding on water quality, and reproduces much more frequently then other anemones I've encountered with. I used to fed mine half a frozen cube when I am feeding other anemones. You'll have to drop the cubes directly onto their mouth. Their tentacles are not paticularly sticky thus are not a good idea to let their tentacles do frozen food catching tasks. I kept mine under MH, but I doubt they are photosynthetic. As their base are burried under sand and attached to base rocks, I wouldn't really know if they reproduce by splitting, budding, or sexually, but when I was moving my tank, I did found 7 tube anemones total from 3 I originally purchased. Several of them are firmly attached to rocks and I had to sell the entire base rock back to LFS fearing I would severly injur them by tearing them off from the rocks.
