Datnioides undecimradiatus (ROBERTS & KOTTELAT, 1994)

Mekong Tiger Perch

October 28th, 2015 — 4:53pm

An efficient, largely piscivorous, predator with highly protrusible mouthparts. In the aquarium, juveniles can be offered chironomid larvae (bloodworm), small earthworms, chopped prawn, and suchlike, while adults will accept strips of fish flesh, whole prawns, mussels, live river shrimp, larger earthworms, etc. Older individuals do not require feeding on a daily basis, with 2-3 times per week sufficient.

Datnioides pulcher (KOTTELAT, 1998)

Siamese Tiger Perch

October 28th, 2015 — 2:51pm

The massive decline in wild populations, hypothesised to be in excess of 90% since the mid-1980s, is thought to have been caused by a variety of factors, including habitat alteration due to construction of dams and other infrastructure, removal of riparian vegetation, and urban pollution, plus over fishing for both human consumption and the aquarium trade.

Datnioides polota (HAMILTON, 1822)

Silver Tiger Perch

March 13th, 2012 — 1:18pm

D. polota is sometimes referred to as D. quadrifasciatus (Sevastianov, 1809) but the original name of the latter, Chaetodon quadrifasciatus Sevastianov, 1809, is a junior primary homonym of the older Chaetodon quadrifasciatus Bloch & Schneider 1801, thus Coius polota Hamilton, 1822 takes precedence.

Datnioides microlepis BLEEKER, 1854

Indonesian Tiger Perch

March 13th, 2012 — 1:18pm

In aquarium literature this species is also referred to as ‘fine scaled tiger fish’, ‘Indonesian tiger fish’, ‘Sumatran tiger fish’, ‘Indo datnoid’, and ‘Indo dat’. The common name of ‘tiger fish’ is also used in reference to the African alestid genus Hydrocynus, and the more appropriate ‘tiger perch’ was suggested by Roberts and Kottelat (1994).
