[edit] Alternative Names
- Somphongs's Rasbora
- This species was described and named by Meinken in 1958, and reclassified by Kottelat & Witte into the genus Trigonostigma in 1999.[1]
- This species common name Somphongs's Rasbora comes from the Somphongs Aquarium Company. [2]
[edit] Synonyms
- Rasbora sompongsi
[edit] Origin
- A rare fish native to Thailand. Possibly found in the Menam (Chao Phrya) river basin, but also reported found in the nearby Mae Klong river basin within Ratchaburi.
[edit] Sexing
- Gender ratios are generally unimportant unless breeding is desired, and sexing is difficult. Females may be slightly larger and posses a rounder belly.
[edit] Breeding
- Unlike most Cyprinids, which are “egg scatterers”, members of the Triginostigma genus attach their eggs to the underside of broad leaves. Spawning in home aquaria is unlikely as this species requires pristine, acidic, and very soft water for successful breeding, and fry require microfoods. For more information see: Breeding Trigonostigma.
[edit] Tank Compatibility
- Like many other small schooling species it is recommended to keep in larger schools of 10 or more individuals when possible to help reduce shyness. A tank length of at least 24" is recommended to allow adequate movement for the school. Avoid all aggressive species, as well as larger and/or overly active species that may consume or frighten T. somphongsi.
[edit] Diet
- Should accept crushed flake, micro pellets, and very small dried, frozen, or live foods. Cyclops, small mosquito larvae, and young Brine Shrimp also readily taken.
[edit] Feeding Regime
- Feed one to two times daily
[edit] Environment Specifics
- Thrives in soft, slightly acidic water. Appreciates a heavily planted tank with dark substrate, use floating plants as this fish doesn't appreciate bright lighting.
[edit] Behaviour
- A mid-top swimming fish which is a shy, peaceful schooling species.
[edit] Identification
- Smallest fish in the genus, and lacks the traditional wedge body shape. The body is mostly transparent with orange colouration in a pattern similar to Trigonostigma espei, and the fins are clear with exception of the caudal fin that may have triangular orange colouration. The peduncle mark is even thinner than that of Trigonostigma hengeli, and is a line shape that is slightly broader towards the anterior.
