    Tan, J. Y. H., L. H. C. Tan, G. Quek, V. S. F. Lim & H. H. Tan, 2013. The fish fauna of Bukit Brown, Singapore. Nature in Singapore, 6: 229237.

    Abstract: Two streams at Bukit Brown, a traditional Chinese cemetery, were surveyed for fishes. Of the 11 species found, seven were from Bukit Brown Stream, and nine from Mount Pleasant Stream. Seven of these species are alien and likely to have been artificially introduced there. Feral populations of the zebra danio (Danio rerio) and the paradise fish (Macropodus opercularis) are reported from Singapore for the first time.

    The species recorded in these streams comprises an interesting mixture, and most of them are found in the aquarium trade:

    NON-NATIVE
    Pearl danio (Danio albolineatus) (See also my observations in another thread)
    Zebra danio (Danio rerio) (Also, a suspected pearl danio X zebra danio hybrid was collected!)
    Indochinese spotted barb (Systomus rhombeus)

    Guppy (Poecilia reticulata)
    Platy (Xiphophorus maculatus)
    Sunset platy (Xiphophorus variatus)

    Paradisefish (Macropodus opercularis)

    NATIVE
    Common walking catfish (Clarias batrachus)

    Asian swamp eel (Monopterus albus)

    Marbled gudgeon ('soon hock') (Oxyeleotris marmorata) (Likely introduced)

    Forest betta (Betta pugnax) (Likely introduced)

    Like the paper mentioned, it is interesting that many common open-country species, such as the native pygmy halfbeak, blue panchax, croaking gourami, three-spot gourami, climbing perch, common snakehead ('aruan'), and the introduced Mozambique tilapia, are all missing from these streams, which are actually concrete drains that have since been reclaimed by nature. It is possible though that some of these were actually present but weren't caught and recorded
    Small is beautiful.

    Very informative exploration trip. If only Singapore has more of such natural habitat to balance our hectic lifestyle than being replaced by artificial garden to entertain the rich-only people.
