a month or so I posted about my leathers sweepers.well, I decided to keep the coral as the sweepers do not seem to bother the corals anymore. Anyway , they sweepers are up to about two feet maybe 30 inches and they are out 24/7 this thing is a real beast. Copepods, mysis even baby cleaner shrimp constantly. Pretty much the greatest thing ever in a reef tank.Anyone who would like to see it .I welcome guests as enjoy showing off my tank.I am hoping i will get the opportunity to host a meeting.Anyone who said leathers don,t have sweepers well come see.
