''Rhodeus'' is a genus of freshwater Actinopterygii, ray-finned fishes belonging to the Family (biology), family Acheilognathidae, the bitterlings. The Binomial nomenclature, scientific name is derived from the Greek language, Greek word ', meaning "rose". Most species in the genus are restricted to Asia, but two species are found in Europe (''R. amarus'' and ''R. meridionalis''). Bitterlings are short-lived species, generally surviving only about five years. Their maximum size is 11 cm, but they are usually much shorter. Bitterlings inhabit slow-flowing or still waters, such as ponds, lakes, marshes, muddy and sandy pools, and river backwaters. Because they depend on freshwater mussels to reproduce, their range is restricted. Bitterlings are Omnivore, omnivorous, feeding on both invertebrates and plants. Bitterlings have a remarkable reproduction strategy where parents transfer responsibility for the care of their young to various species of freshwater mussels (Unionidae an ...

Rosy Bitterling
The rosy bitterling or Tairiku baratanago (''Rhodeus ocellatus'') is a small freshwater ray-finned fish belonging to the family Acheilognathidae, the bitterlings. This species occurs in East Asia from the Amur River basin to the Pearl River basin. Females are about long and males are . Their bodies are flat with an argent-colored luster. However, males change to a reddish (sometimes purple) color during the spawning season (March to September) which functions to attract females. This reddish color is similar to the color of a red rose, which is why it is called a rosy bitterling. Ecology and reproductive system Rosy bitterlings live in ponds (reservoirs) where freshwater mussels are abundant. Farm ponds are an important habitat for not only rosy bitterlings, but also mussels and plankton. Freshwater mussels play an important role in rosy bitterling reproduction. The female rosy bitterling has a unique pipe about the same length as its own body, used for laying eggs on a specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
