yup, its called bio-devesity. If you get a bunch of lr from all over the world your gunna have many different life forms in your tank. So You can get the bulk of your rock from one place, lets say fijji, but leave some room in your tank so the next time you go to the lf and see a nice peice of tonga you will have room in your tank for it. If one of your buddys has a saltwater tank you and him can trade lr peice's.
what about cultured live rock, i would love to care for the environment but i can only find cultured live rock online for around 40+ pounds which i think is too much for my tank. I dont know anyone near me who has a saltwater tank sadly.
