Sicyopterus Jongkas Goby – Rare Freshwater Stream Goby
The Sicyopterus Jongkas Goby is a fascinating and uncommon freshwater fish known for its streamlined body, specialized sucker-like pelvic fins, and unique rock-clinging behaviour.
Adapted to life in fast-flowing streams, this remarkable goby spends much of its time resting on smooth rocks, grazing on natural biofilm, and exploring its surroundings.
Its distinctive appearance and natural behaviour make it an exciting addition to a carefully designed river-style aquarium.
Unlike typical community fish, this species requires clean, highly oxygenated water, strong circulation, and mature rock surfaces that support natural algae and microorganisms.
An excellent choice for experienced aquarists who appreciate rare freshwater gobies and natural stream aquariums.
