Hey, does anyone have any experience with Maccullochi Rainbow (Melanotaenia maccullochi) LFS just received 12 of them (they know to call me when they get something different), I've kept many different types of rainbows but never these , just wanted some reputable information on them. Also does anyone know how to sex them at a young age? I enjoy keeping many deferent fish , that I haven't previously, hence why I have 8 Tanks and 7 Betta 5g tanks. Thanks In advance. @NavigatorBlack @chromedome52 or Anybody else?
