The foot is a brownish red, so I guess rust would be more appropriate. I just talked to my buddy who gave him to me, and he said he collected it from under a dock in Port Canaveral, FL. He had also given me a few life filled rocks with some smaller reddish anenomes on them that have white stripes on the tentacles. I haven't bought any fish for the tank yet, so I am going to run with this little "experiment" first, and if things stay stable, look into adding my fish a week or two down the road. Oh, and yes, it is cycled. I just hadn't added anything yet.
10 Gallon FOWLR (and macro-algae)
20 Gallon Low-tech planted FW
