Editing Trigonostigma espei

|origin=:This fish is native to Cambodia, and Thailand. A schooling species which most commonly inhabits soft, acidic bodies of water with lush plant growth, including pools, ponds, marshes and swamps. In the Mekong River of Cambodia these fish are caught for the aquarium trade by local fisheries using seines and traps.<ref name="lao">Rainboth, W.J. (1996) <u>Fishes of the Cambodian Mekong. FAO Species Identification Field Guide for Fishery Purposes.</u> FAO, Rome, pgs. 4, 77. ISBN 92-5-103743-4 [http://www.fao.org/docrep/010/v8731e/v8731e00.htm Available Here]</ref> Unlike the [[Celestial Pearl Danio]] this species has not been threatened by collection for the aquarium trade, but may one day face loss of habitat to forestry and agriculture.<ref name="trig">&Aring;

|sexing=:Specific gender ratios are not important unless breeding is desired, and sexing can be difficult.  Like some other species of ''Rasborinae'' the females may be slightly larger than the males, and posses a more rounded belly.  Males may be more colourful,<ref name="atlas" /> and have a downward point on the "lamb chop", where the females mark may be more rounded.<ref name="trig" />

|tank_compatibility=:Swims primarily in the mid to upper levels of home aquaria, and will readily eat from the water surface.  Keep in a minimum school size of 8-10 for the best displays of schooling behaviour. Because these fish are somewhat active, a minimum tank size of 20 gallons is recommended for beginners, and 10 gallons minimum for more advanced fish keepers. Acceptable tank mates include other small [[:Category:Cyprinids|Cyprinids]], peaceful [[:Category:Dwarf Cichlid|Dwarf Cichlids]], [[:Category:Corydoras|Corydoras]], and smaller species of [[:Category:Gourami|Gouramis]].

|diet=:Will readily accept any small prepared, dried, frozen, and live foods.  Choices include crushed flake, micro pellets, small [[brine shrimp]], [[mosquito larva]]e, and [[daphnia]].

|feeding_regime=:Feed once or twice a day.

|environment_specifics=:This species does require soft, acidic water to breed and but can tolerate moderately hard and alkaline water parameters as long as good water quality is maintained.  Well planted tanks are recommended to provide both shade and hiding spaces, dark substrates to encourage best colouration, and with low to moderate water current.

|behaviour=:An active, and peaceful schooling species.  Seem to enjoy spending some time "playing" in water currents created from filter outputs and water changes.

|identification=:Young and juvenile fish will look very similar to ''[[Trigonostigma heteromorpha]]'' or [[Harlequin Rasbora]], and ''[[Trigonostigma hengeli]]'', but the size and colouration of adult fish assist in differentiation.  An adult ''T. espei'' is smaller than the former, possessing a bright bronze to copper iridescent colouration similar in distribution to ''T. heteromorpha'', as well as intensely coloured eyes, and yellow to orange triangular colourations on the [[dorsal]] and [[caudal]] fins,  but possesses a slimmer “lamb chop” shaped mark on the peduncle,<ref name="lao" /> whereas the ''T. hetreromopha'' has a rosy colouration, and the hatchet mark is much larger and triangular.
