Paratanakia chii – Super Rare Freshwater Bitterling
The Paratanakia chii is an exceptionally uncommon freshwater bitterling, prized by dedicated aquarium enthusiasts and collectors of rare Asian fish.
This fascinating species is admired for its delicate body shape, subtle iridescent coloration, and unique natural behaviour. During breeding periods, mature males may develop more noticeable coloration, adding to their appeal.
Unlike many common tropical aquarium fish, bitterlings have a remarkable reproductive relationship with freshwater mussels, making them particularly interesting to aquarists who appreciate unusual aquatic species.
Best suited for experienced hobbyists, Paratanakia chii requires a carefully maintained aquarium with stable water conditions, gentle hiding areas, and compatible peaceful tankmates.
A distinctive addition to a specialized freshwater collection.
