While I agree that some were not as nice as they could have been. Me maybe being one of them. You did ask a question though, and you did get answers. All of us like SW fish and the hobby, you included, when saying that it is illegal to take anything from the beach or telling you that it may not be a good idea because it could have a detrimental effect on your tank is just concerns for you, the hobby, and the natural enviornment. No one is meaning to "bash" you, when you ask a question to many people you will get many answers. Some you may not like, some that you may. You must keep in mind if asked by a police officer why you are taking live stock out of the ocean illegaly, saying im trying to save money wont change the law. Polutants are a major factor of life, it is hurting the enviornment and is everywhere. If polutants would destroy nature, why would it not destroy your tank and all of the inhabitants in it? Like I said, sometimes you may not get the answer you like, but everything should be took into account with something this important in your tank. No one is bashing, just giving oppinions.
