they are related, and are both danios. some fish stores still list them under the old names. they will act almost identical, and are pretty skittish. dimmer lighting \ plant cover on the surface will help them feel more at easeRecently managed to purchase 4 Emerald Dwarf Rasbora's (yet, classified as Danio's?) from my LFS in the hope they shoal with the 7 CPD's in my tank. Why are these fish under different Genus'?
They're nice looking fish, especially the males colour palette - appearing to be blue, not green? They also hide like crazy, something I was expecting as my initial pack of CPD's took weeks to show their true characters.
The EDR/D's swim rather jittery as well, constantly fluttering their fins as opposed to the CPD's gracious float.
Has anyone had any experience keeping the Emerald Dwarf Rasdanio?
