Amen, my purple tip is in fact a brown Sebae as stated above and when I bought it it had been bleached out. It was pure white with purple tips.
It took months for it to turn brown again, for while I didn't think it was going to make it.

If you can wait....if/when he clones/splits I can give you one of them...but I have no idea how long that could be.....my parents are in Wetaskiwin so they seem to like it when I come to visit ....

ponokareefer,

My experience with my RBTAs is that all 5 clones I've had wander to find a spot where they can sink there foot into a crevase or hole in the side or underneath a rock and then expand out from it. None of mine have every left there crevase once settled except when they clone. You should try NOT to change your flow though in your tank, as that can trigger them to move (do this if you want to move them however).

They do sting some corals, just recently had to move a colt as my RBTA had killed one side of it as the RBTA is growing faster and needs more room. It doesn't hurt my flowerpot, zoos or mushrooms all around it otherwise though. Its tentacles are mostly away from those corals and rock however.

Good luck with one!
