That's Dave Colling's site. He's been breeding rainbows for 15+ years and produces some truly beautiful ones. If anybody is qualified to write a care sheet for them, it's him. (I have no affiliation apart from having talked to him on another forum and REALLY wanting to get at least one of his rainbows some day.)
