Sebaes are similar to M. doreensis in that they bury their column in the sand. Assuming you get a healthy one to begin with, they are generally considered relatively hardy, as anemones go. Hardiness for the commonly imported host species ranges from: BTAs are regarded as the easiest, haddoni would be next, sebae next, then you get to gigantea and magnficas toward the more difficult end of the spectrum. Things like H. malu, mertensii, and H. aurora are not that frequently imported, but I would say each of the last three species fall somewhere in the middle. The pizza anemone is hardly even a host species since it's only found with clarkii, and is seldom seen in the hobby, they are supposedly quite hardy. I may be leaving out a species, but that gives you a general idea of the hardiness of the various host anemones. I would say, even for the more difficult species, the key is getting a healthy animal to begin with...then provide good/excellent conditions (generally that includes a specific gravity of natural seawater 1.026-1.027, reef temps 78-82, low/no nitrates, proper lighting and flow and a substrate that suits the species).
