I just did not want the virtual web hand smack. I contacted vividaquariums.com, saltwaterfish.com, and marinecenter.com. Saltwater said they usually have groups in stock. It could be a gamble if all they wanted was a sell though. I say try locally first then send your $ out of town. If anyone would know how to get some it should be Ross. I just wanted to get my 0.02 cents in on if they could be kept together.
