Glad to hear of your success FAF. Zebra danios are really fun fish. I like the way the dark part of their stripes can sometimes take on a handsome blue component as they become more mature fish. All fish can be strikingly beautiful, even the very small ones, when you are right there with your aquaium and able to at times observe them very, very closely. Its one of the pleasures of fishkeeping! Its also interesting with danios that they can seem like little racing machines, sort of pure muscle and kind of streamlined for low drag.. they seem slightly higher in the middle and very slightly curved lower at the front and tail which to me looks like some of the low-drag things that engineers design.
