It's really sad about the sebaes. The first one I got was dyed pink and it was dead after 2 weeks. It would not eat anything. The second one was a fighter. She was bleached but still had a little faint trace of beige color but what saved her was her appetite. That thing eat like a little pig each day since day one. It's really sad that they inject them with color. I never saw a healthy one at the store either.
Here is mine at the begining, it was 3" with very short tentacles, in starving mode, but that is the best I could find in any store:
After 2 or 3 months it was starting to change, tentacles getting longer and it was getting darker:
And now today after a year of good care and eating a lot, she's 12" and very dark brown body:
