i have an eclipse 12 that houses my mantiss. i only have about 6# of LR, so i have a lot of open area. i would like to add a tube anemone but i'm not sure if the two will co-exist. anybody tried this combination? i realize that the anemone is also a predator and i don't want it stalking my mantiss. in the end, i'm sure that if a conflict arose, they'd both be dead. i am also running about 4-5" of live sand so i think that the anemone would stay put. any info or experiences would be greatly appreciated. if i don't reply in a timely manner, please don't consider me rude. i no longer have regular access to a computer. thanks. damn! sorry about the double post.
