Description
The tabira bitterling is a small, deep-bodied cyprinid of the family Acheilognathidae (bitterlings) reaching about 8 cm. The compressed, silvery body has a bluish lengthwise stripe over the rear half; breeding males colour up vividly with blue and red-orange tints. Characteristic is the special reproduction: the female develops a long ovipositor and lays the eggs in the gill cavity of a living freshwater mussel, where the larvae grow up sheltered - a partnership between fish and mussel. The species comes from Japan and lives in clear ponds, lakes and slow-flowing rivers where such mussels occur. It eats algae, zooplankton, insect larvae and detritus. It is popular in the coldwater aquarium hobby.
