I need some really good live rock covered in coralline to help seed my new tank. My problem is, i'm located in a rural area were there is only one LFS that sells saltwater fish and inverts. They have the live rock that i need to seed my new tank but most of there live stock has ICK. Very apparent the fish are sick and sometimes dead. My question is should i go ahead and buy the rock from these tanks knowing i will be quarantining them anyway? I see people buying fish from this place all the time and i'm just thinking what are they doing with all these sick fish..
