thats awesome, would love to get rid of mine, its getting out of control... did you order males or females? going to place an orderfThese guys are workhorses and have really cleaned my tank up of almost all algae (not just bubble) as I try to bring up my no3 and po4 from bottoming out. They have not bothered any coral and when on or near one they were just cleaning up any algae on frag plug. My tank is lps and sps.
