==Taxonomy==
''Datnioides microlepis'' was first formally [[Species description|described]] in 1854 by the Dutch [[physician]], [[herpetologist]] and [[ichthyologist]] [[Pieter Bleeker]] with its [[Type locality (biology)|type locality]] given as the [[Kapuas River]] at [[Pontianak]], [[Kalimantan]], Indonesia.<ref name = CofF>{{Cof genus|genus=Datnioides|access-date=27 October 2023}}</ref> This taxon was considered to be [[conspecific]] with the [[Siamese tigerfish]] (''D. pulcher''), which was included in ''D. microlepis'' until 1998.<ref name=Kottelat1998>{{cite journal |last=Kottelat |first=M. |title=Fishes of the Nam Theun and Xe Bangfai basins, Laos, with diagnoses of twenty-two new species (Teleostei: Cyprinidae, Balitoridae, Cobitidae, Coiidae and Odontobutidae |journal=Ichthyological Exploration of Freshwaters |year=1998 |volume=9 |issue=1 |pages=1–128}}</ref><ref name=Kottelat2013>{{cite journal |last=Kottelat |first=M. |title=The fishes of the inland waters of southeast Asia: a catalogue and core bibliography of the fishes known to occur in freshwaters, mangroves and estuaries |journal=Raffles Bulletin of Zoology|year=2013 |volume=27 |pages=1–663}}</ref> The 5th edition of the ''[[Fishes of the World]]'' classifies this genus as one of two genera in the family Lobotidae, alongside the tripletails in the genus ''[[Lobotes]]'', which it places in the order [[Spariformes]].<ref name = Nelson5>{{cite book |author1=Nelson, J.S. |author1-link=Joseph S.

==Etymology==
''Datnioides microlepis'' has the [[Specific name (zoology)|specific name]] ''microlepis'' which means "small scales", an allusion to the smaller scales of this species compared to ''[[Datnioides polota|D. polota]]''.<ref name = ETYFish>{{cite web |url=https://etyfish.org/eupercaria/ |title=Series EUPERCARIA (Incertae sedis): Families CALLANTHIIDAE, CENTROGENYIDAE, DINOPERCIDAE, EMMELICHTHYIDAE, MALACANTHIDAE, MONODACTYLIDAE, MORONIDAE, PARASCORPIDIDAE, SCIAENIDAE and SILLAGINIDAE |work=The ETYFish Project Fish Name Etymology Database |access-date=26 October 2023 |date=9 March 2023 |publisher=Christopher Scharpf |archive-date=17 February 2022 |archive-url=https://web.archive.org/web/20220217162719/https://etyfish.org/eupercaria/ |url-status=dead }}</ref>
==Description==
''Datnioides microlepis'' has the deepest body of the species in the [[genus]] ''[[Datnioides]]'', its [[standard length]] being 2.1 to 2.4 times its depth. The maximum published [[total length]] for this species is {{cvt|55|cm}}, making it the largest species of ''Datnioides''.<ref name =Fishbase>{{FishBase|Datnoides|microlepis|month=June|year=2023}}</ref><ref name = Fishbase2>{{FishBase genus|genus=Datnioides|month=June|year=2023}}</ref> It may be identified from its [[Congener (biology)|congener]]s by having 6 or 7 broad dark vertical bars on the body, with a yellowish-grey background colour. The band nearest the head typically runs unbroken over the [[Operculum (fish)|operculum]] and over the throat. There is an obvious black marking just in front of the base of the [[pelvic fin]]. The part of the back in front of the dorsal fin is straight.<ref name=SeriouslyFish>{{cite web| title=Datnioides microlepis Bleeker, 1854 Indonesian Tiger Perch | url=https://www.seriouslyfish.com/species/datnioides-microlepis/ | publisher=SeriouslyFish | accessdate=5 January 2020 }}</ref>
==Distribution and habitat==
''Datnioides microlepis'' is found in [[Sumatra]] and western Kalimantan on [[Borneo]] in large lowland rivers, sometimes entering brackish waters.<ref name=Coius/> It often prefers areas with an abundance of submerged branches and is found in flooded forests.<ref name = Fishbase/> Records of this species from the [[drainage basin]]s of the [[Chao Praya]] and [[Mekong]] are thought to refer to the Siamese tigerfish.<ref name = SeriouslyFish/>
==Biology==
''Datnioides microlepis'' is a predatory species, adults feed on crustaceans and smaller fishes, as well as [[annelid]]s and insects, while juveniles feed on [[zooplankton]].<ref name = Fishbase/> Adults are solitary and aggressive to other members of its species while the juveniles will gather in groups.
