Thanks. I found Garra pingi pingi being sold as a 'coldwater log nose sucker'. After finding Garra rufus available (through ebay, not too sure about online delivery of fish), I wondered about them as they're slightly smaller. But if they're tropical, that's out for the tank I am planning. If the description of 'Garra pingi pingi' as 'coldwater' is inaccurate, I'd like to hear about that. I found a source for Garra flavratra asl, but on researching them found them to be definitely tropical. From Burma/Myanmar, albeit mountain regions. Garra rufus appear to be from Syria, Iran, Turkey, etc.
