High Quality Content by WIKIPEDIA articles! The Celestial Pearl Danio, Danio margaritatus - often referred to in the aquarium trade as galaxy rasbora or "Microrasbora sp. 'Galaxy'" - is a small cyprinid from Myanmar. It has so far been found only in a very small area near Hopong east of Inle Lake, at an altitude of over 1,000 m (3,400 ft). Its habitat is part of the Salween basin, namely the Nam Lang and Nam Pawn rivers. Discovered in 2006, the species quickly appeared in the aquarium trade, where its small size and bright colours made it an instant hit. This is a small plump danionin with a markedly blunt snout, measuring just 1.5-2 cm standard length. The body is about three times as long as it is high. In general shape, it resembles "Microrasbora" erythromicron more than any other known species. This species shows some sexual dimorphism: males have a bright blue background color (dull blue-green in females), and their fins are more brightly colored. The tail end of their bodies (the caudal peduncle) is also higher than in females. The body is sprinkled with small, pearly dots. The back is bronzy green, and the belly in females is yellowish-white.
