Trigonostigma somphongsi (MEINKEN, 1958)

March 13th, 2012 — 1:24pm

T. somphongsi is exceptionally rare both in nature and the hobby and was considered potentially extinct for around a dozen years before a trio were imported to Germany as contaminants among a batch of Boraras urophthalmoides in 2006.

Since then it has been successfully bred and distributed to various experts, mostly in Thailand and Germany, in the hope of establishing a sustainable captive population. The possibility of a…

Trigonostigma hengeli (MEINKEN, 1956)

March 13th, 2012 — 1:23pm

T. hengeli is sometimes seen for sale with the trade name of ‘glowlight rasbora’ due to the distinctive orange patterning on the posterior part of the body but we’ve refrained from using that name here because it’s also commonly applied to Trigonopoma pauciperforatum.

As it places no extreme demands in terms of water chemistry it can be combined with many of the most popular fish in the hobby including other small cyprinids as well as tetras, livebearers, dwarf cichlids, catfishes, and loaches. As always when selecting a compatible community of fish thorough research is essential and its small adult size must be a consideration, however.

Trigonostigma heteromorpha (DUNCKER, 1904)

Harlequin

March 13th, 2012 — 1:18pm

T. heteromorpha was first exported for aquaria in the early 1900s and has gone on to become one of the most familiar, enduring species in the hobby. It has suffered as a result of its popularity to a certain extent with the mass-produced fish we see today lacking much of the colour seen in wild specimens and even exhibiting morphological deformities in some cases.

Several selectively-bred ornamental strains have also…
