I'm sorry to stray away from the topic more, but I just want to take this opportunity to learn something and correct me if I'm wrong. The reason for the relationship in the wild with anemone and clown, is because its beneficial to both right? The clown has more exposure to predators which encourages it a lot where in a tank (especially with tank bred clowns) they don't feel as threatened and aren't more apt to host one. I've actually seen a clown in a LFS
hosting a type of coral, not sure what type.
