|   Honestly, I gotta ask why? There are so many suitable macros available, probably free for the asking. With the crap I see along the shoreline, I wouldn't ever think of adding it to my tank.

|   they wouldn't live much longer than a couple of weeks. Need a coldwater tank, that means chiller to maintain about 50-55 degrees F. I actually kept a barnacle covered rock in a sw tank ( about 15 yrs ago) and it managed to live about a month. Really cool to watch the barnacles open up and the tongues come out.

|   I would recommend against even trying. Unless you are very knowledgeable about the various seaweed species along the coasts and their various tolerances (there are some good books on the topic, I looked into this myself when I first got into the hobby) or unless if you are trying a coldwater tank. The problem is a lot of them can release enough toxins to kill everything if for example they get too warm. A few years back I found a really good book on the subject, I'll see if I can find it and post the title, it makes for an interesting read particularly if you're into finding out "what is this whatzit" that you can find on shoreline walks..

|   Thanks everyone, it was more just a question to see if anyone has ever tried it! |
