[Nebthet]

Thanks for uploading some pictures. If it is beginning to attach to a rock that is a good thing. Allow it to do that.
From picture number two, thankfully your sebae still has a little bit of it's brown color. Not much, but it is better than having non at all. This means it will be a little easier to bring it back to health but it will still take a long time.

Please remember to keep a lot of room around these anemones. They often grow to be around 20inches in size, not including the tentacles.

Feed this guy every other day for at least 4 months. You should start seeing the brown color darken, and then slowly spread out to the other tentacles. Shrimp, clams, squid, are all good if finely chopped up.

Please keep up updated on the changes with this sebae.
