Rosy bitterling is an invasive species from the continent of China.

They live in shallow ponds and mild current rivers.

During breeding season, the back of the male turns turquoise and the area from its head to stomach turns red, which is very beautiful. Its name comes from the red color seen during this season.  Rosy bitterling and other fish of the same bitterling family lay eggs on clams using narrow tubes called ovipositors.
