Emerald Dwarf Rasbora - Celestichthys erythromicron
Also known as the Emerald Dwarf Danio. Originally known scientifically as either Microrasbora erythromicron or Danio erythromicron.
One of the most beautiful and sought after fish for planted tanks. Does well in planted aquariums with small shrimp.
They get along well with their close relative, the Galaxy Rasbora/Celestial Pearl Danio and do not grow very big either.
Size is about 1/2 inch to 3/4 of an inch.
