Stickyness is the nematocysts firing into your fingers...If you were a small fish, it would then haul you in for a meal! Use extreme caution when handling/touching an anemone that you wash your hands very well afterwards, and DON'T touch your eyes or other sensitve areas! the nematocysts can still hurt you, even though you may not feel them in your fingers!
As for your sebae...it looks like its surviving, but still severely bleached. It will have an uphill struggle to survive long term, but with proper care, it should make it. Light is VERY important for anemones, and since your's has lost it's zooxanthellae algae in it's tissues, YOU will have to supplement it's feeding more carefully than with a healthy anemone. Chop pieces of silversides, dinner shrimp from the grocery store, or other NON-oily fish into tiny pieces. (about 1/4" cubes) and feed every 2-3 days. You can soak the foods in Selcon or Zoecon, (both nutritional supplements) if you choose, but it's not required.
Sebaes (especially bleached ones) have a poor survival record in aquariums. YOU, as well as the anemone have a long hard fight ahead...
