Six Emerald Dwarf Rasboras bred in the hard suburban tap water of my fishroom.  The adults are small, these ones in the auction are even smaller, about 1/2 the adult size.  Great for a micro tank or a tank with any size shrimp.  Known for hiding unless you have a large group.  I have them mixed with schools of Ember tetras and Kubotai rasboras and they're always out front and center as part of this group of +24 small fish.  They've been fed BBS and Golden Pearls as soon as their mouths were large enough.
