Carinotetraodon salivator LIM & KOTTELAT, 1995

December 1st, 2015 — 4:58pm

It is included in a group often referred to as ‘red-eyed puffers’, which currently contains four recognised species distributed in Indochina and the Greater Sunda Islands. It can be distinguished from C. borneensis, C. irrubesco, and C. lorteti, the remaining members of this group, by the following combination of characters: 11 dorsal-fin rays; 16 pectoral-fin rays; 11-13 anal-fin rays; 11 caudal-fin rays; eyes not bulging above the head; in males dorsal-fin hyaline, black spot on dorsal-fin base present, pectoral-fin base hyaline, anal-fin hyaline with no black spot at base…

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.

Macropodus hongkongensis FREYHOF & HERDER, 2002

In 1996 the species was known from five localities in Hong Kong, but at least one of these has been destroyed and it is now known only from Tai Po and Sai Kung districts. Additional populations have subsequently been discovered in Guangdong and Fujian provinces on the southern Chinese mainland.

Type locality is ‘China: Hong Kong: Tai Po: Sha Lo Tung’.

Macropodus erythropterus FREYHOF & HERDER, 2002

September 30th, 2015 — 4:43pm

This species is frequently mistaken for the similar-looking congener M. spechti Schreitmüller 1936, which is easily-identified by the absence of reddish pigmentation in the dorsal, anal, and caudal fins. There has been some debate as to whether these two represent the same taxon, however, with Winstanley and Clements (2008) proposing that M. erythropterus be considered a synonym of M. spechti because they were unable to separate the two species by morphological characters, and specimens with red pigmentation on the unpaired fins were coll…

Pygocentrus cariba (HUMBOLDT, 1821)

Black Spot Piranha

September 27th, 2015 — 1:23pm

Has been recorded from major river channels, smaller tributaries, and floodplain lakes, many of which comprise acidic, mineral-poor blackwater environments with brownish, tannin-stained water, although it has been observed to inhabit clear waters as well.

Many of its habitats lie within the Venezuelan and Colombian llanos, a vast, highly biodiverse system of tropical savannah grasslands, seasonally-flooded plains and forests covering an area measuring almost 600,000 square kilo…

Betta miniopinna TAN & TAN, 1994

September 10th, 2015 — 12:48pm

Bintan has been developed for tourism over the last decades and is heavily-promoted by Indonesia, with luxury beach resorts and golf courses increasing in number. Further deforestation has occurred in order to establish large rubber plantations in the interior of the island. B. miniopinna is now restricted to a few remaining pockets of primary peat swamp forest and has been listed as ‘Critically Endangered’ on the IUCN Red List of Threatened Species since 1996.

Cyphotilapia gibberosa TAKAHASHI & NAKAYA, 2003

September 8th, 2015 — 3:37pm

Prior to the description of C. gibberosa in 2003 the genus Cyphotilapia was considered monotypic for almost a century. Members are separated from other cichlid taxa inhabiting Lake Tanganyika by possession of a hump on the forehead and broad vertical bands on the body, although the latter tend not to be visible in large males.
