Rasboras are all you need to fill your tank with living color. Few freshwater tropical fish are as bright, animated, peaceable and easy to care for. Members of the same Cyprinid family as tetras, rasboras come from south and southeast Asia where they live in slow moving streams, dense with vegetation. When well-fed (and these little fish can eat a great deal) and in good condition, these fish display sharp bright background hues, that seem to be illuminated from within.
