Rasbora pauciperforata, they're great little things. A bit shy, but if they have a lot of plants where they dodge in if they feel threatened, they do fine. Totally peaceful, eat all the regular foods. When spawning, the male turns a very dark brown above, almost black with the red line shining, awesome sight.
Although the adults can tolerate a wide range of water conditions, the fry don't survive above pH 6. At about 15mm they can be weaned into whatever you are using in your display tanks.
