Hey, man. Frankly speaking, live rocks can't be find in the every zoo magazine, and even if you have found the live rocks, they will cost much more, then their real cost. Local zoo magazins make money on the people's laziness, who don't want to find the same good in the internet. You can say, that they win in time, but frankly speaking, I don't realy think, that 2-3 days matter. What is connected to Ali, I don't like this source, because of its incompetence, I am talking about the situations, when the good comes to you 3 weaks, insted of 4 days, or when it comes to you broken or when it doesn't come at all. I would better chose to buy them at
arcreef, where you can order the live rocks for the same price, like on ali, but you will sure, that the good will come to you safe and sound. Of course, It's your business, where to buy them. I just wanted to give you advice.
