A LFS has a "big" (4") CL for sale, three inches is about the max I've seen for sale. It's 30 bucks but is a loner. Is it worth buying knowing it will be a loner in my tank for a few months. I have four 1.5-2" in a growout situation and can't put them in the main tank yet. Will this loner be OK by himself for a while? Or should I pass?
