OK folks, let's keep this friendly and simply answer the questions. Keep it on topic and no attacks.
FWIW, I agree with James statement above, 1 species per tank, they will sense each other as soon as they hit the water and chemical warfare will begin. Anemones, also, are not sessile inverts, they are mobile inverts and can easily go after one another taking out anything inbetween, lot's of collateral damage. Now, everyones experience, will vary, but you should know that anemones are virtually immortal in the wild, yet fare very poorly in the aquarium. This is why people get so worked up about it. Think about it, what is important to you that is immortal? Suppose they took that away from you after only 3-4 years, or in most cases less than a month?
I'm tagging along on this one, and if there is another post that I consider to be antagonistic or off topic, this topic will be locked. It is unfortunate that we pride ourselves in being one of the friendliest sites on the net, yet I have had to threaten to lock a couple of topics within a week. Please keep your emotions out of your posts, if you can't...don't post! Informational, non-emotional posts are what is needed in this type of situation
