So after my last sebae died, I had a guy offer me another one. It looked pretty healthy so I took it off his hands. I am trying to get it healthy to put in my 90. The base is brown/purplish, and the body off the nem is brown, disc has a green glow under actinics, and the tentacles are brown. Pic is right after I put it in the tank. It is probably close to 10" in diameter.
