thats good someone is coming by to pick them up, definitely doesn't seem right just to throw them away. I agree, I like them as well, they are pretty and grow great, can just get away from you if you arent careful. I usually just picked the branches off the sand, and placed them in the back of the tank behind rock. As stated before, they will grow anywhere. I think anybody just starting a reef tank should get some just to stay motivated seeing something growing!
