    Gastromyzon (& other fish) of Batang Sadong basin

    Borneo island is the only place on earth where you can find Gastromyzon. (common name is Borneo sucker fish / hill stream loach) It is a bottom dwelling fish which has a very unique suction cup formed by it's fins and body. This suction cup enables the fish to cling on the rock surface in the fast flowing streams of Borneo.

    I found my first Gastromyzon on my outing trip in a river of Bau area, more than 15 years ago. At that time, I thought it was sucker catfish / Pleco (from South America) which is very common fish that you can find in any fish shops all around the world. In fact, there is no relationship at all between Pleco and Gastromyzon.

    A clearwater river which is a tributary of Batang Sadong. I managed to photograph Gastromyzon and other fishes in very close distance on this spot without scaring them away.




    Gastromyzon farragus and a school of Paracrossocheilus vittata are grazing for algae growing on the rock.

    Gastromyzon scitulus (dorsal view)

    A tadpole of a species of a frog is also got this special suction cup to adhere on the rock. On its right is Gastromyzon farragus.




    Tadpole. (ventral view)




    Betta taeniata, a species of wild fighting fish. (female)




    Hill stream catfish. Glyptothorax major.





    Glyptothorax major has a unique thoracic adhesive organ enables the catfish to adhere the rocky substrate in the fast flowing stream.




    Homaloptera weberi also can adhere to the submerged rock on fast running stream.

    Gastromyzon farragus. This one has a little bit different of coloration compared with the normal one.




    Paracrossocheilus vittata has the ability to cling on the submerged rock too.




    Close-up view of the head. Take note that it has very large conical tubercle on each side of the snout.





    Gastromyzon crenastus. This one is only 2cm long. I find it difficult to take a good shot on this one as the size of this fish is too small and my camera can not get too close to the water surface.





    G. farragus and G. scitulus.

    mikey, I need you to set up a company and pretend to sign up as my business partner so I have an excuse to go to Kuching
    why I don't do garden hybrids and aquarium strains: natural species is a history of Nature, while hybrids are just the whims of Man.

    tadpoles

    tadpoles probably belong to genus Meristogenys, a typical hill stream frog species.

    On the contrary

    On the contrary, I have much to learn from you all as I have been out of aquaristic circle for too long and much more to learn about fish photography.

    Southern China also got "relative" of Gastromyzon. They also looks like Gastromyzon, but genus name is different.

    ruby red gastromyzon

    G. katibasensis is supposed to be bright red, but losing colouration rapidly upon death.

    Not seen a good pix of a live specimen yet. See preserved specimen.
