Pseudosphromenus cupanus (CUVIER, 1831)

Spiketail Paradisefish

February 23rd, 2014 — 5:02pm

This species is most easily told apart from its only congener P. dayi by lacking (vs. possessing) two dark, irregular lateral stripes on the head and body, and a shorter caudal-fin in males.

The results of phylogenetic analyses by Rüber et al. (2006) suggest that Pseudosphromenus is most closely-related to Malpulutta in an evolutionary sense.

Channa diplogramma (DAY, 1865)

Malabar Snakehead

July 2nd, 2013 — 7:43pm

This species was considered synonymous with the Indochinese congener C. micropeltes for over a century before being revalidated in 2011.

Like in C. micropeltes colour pattern varies depending on the age of the fish.

Juveniles possess two longitudinal black stripes on the head and body with the are…

This species is euryhaline and mostly inhabits lowland, often coastal, habitats containing still or slow-moving brackish or freshwater.

This species is traded under several names including ‘royal danio’, ‘blue-spotted hill trout’, and ‘blue-dotted mirror fish’.

It can be distinguished from congeners by possessing a single row of bluish-green spots along the length of the body, white margins on the dorsal and anal fins, 37-38+1 lateral line scales, and fleshy rudi…

Puntius mahecola (VALENCIENNES, 1844)

March 13th, 2012 — 1:24pm

This species has a chaotic taxonomic history with certain issues still to be resolved. While the name P. mahecola was misapplied to members of the genus Dawkinsia for over a century the fish itself has been widely misidentified as the congener P. amphibius (Valenciennes 1842).

Its identity was partially resolved by Pethiyagoda and Kottelat (2005b) who demonstrated that though valid P. mahecola is not a Dawkinsia spp. but rather a smaller, relatively plain species with a single dark blotc…

Xenentodon cancila (HAMILTON, 1822)

Freshwater Needlefish

March 13th, 2012 — 1:22pm

X. cancila is often seen referred to as ‘freshwater garfish’, and although it does superficially resemble the true gars of the family Lepisosteidae, it’s actually a member of the Belonidae, or needlefishes, the majority of which are marine or estuarine in existence.

There are currently just two species in the genus although the probable existence of a third member has been noted by Roberts (1989) among oth…

Etroplus maculatus (BLOCH, 1795)

Orange Chromide

March 13th, 2012 — 1:18pm

Wild examples are rarely-seen in the aquarium hobby although selectively-bred ornamental strains are widely-available for which care is identical.

These are normally traded as ‘red’ or ‘yellow’ chromide and have a solid yellow-orange colour pattern with no dark elements.

It exhibits a widespread sympatry with the con…

Etroplus suratensis (BLOCH, 1790)

Green Chromide

March 13th, 2012 — 1:18pm

This species is euryhaline and mostly inhabits brackish estuaries, coastal lagoons and the lower reaches of rivers.

It also occurs in freshwater habitats, however, including a number of inland lakes in Sri Lanka although it appears to have been introduced intentionally.
