Just like we all knows, that fresh water is totally different from sea water. If you done enough observation you will find out that everything from sea is much more colorful, much more artistic. Fish and stone came from sea water is irresistible beauty of nature. But beware those kind of beauty is dangerous for our fresh water habitat. Stones, rocks, sea shells, and sands from sea is contain concentrate lime which is dangerous for tropical fishes. Never put anything from sea into your fresh water aquarium. This is one of the most fatal mistake done by amateur or newbie.
