Espei Rasbora (Lambchop Rasbora)

The Espei Rasbora (Lambchop Rasbora), scientifically known as Trigonostigma espei, belongs to the Cyprinids family group. Adults reach a maximum size of approximately 3 cm and have a compressed body shape with a moderate growth rate. Classified as peaceful, this species primarily occupies the mid-level and surface zones of the aquarium and produces a low level of biological waste.

To thrive, the Espei Rasbora (Lambchop Rasbora) requires a freshwater only aquarium with a minimum volume of 38 litres and a tank length of at least 45 cm. Water temperature should be maintained between 23°C and 28°C, with a pH range of 5.5–7.5 and a general hardness of 1–12 dGH. A low water flow is preferred.

The Espei Rasbora (Lambchop Rasbora) is a rewarding species to keep, provided its core environmental needs are met. The Espei Rasbora (Lambchop Rasbora) is typically available in one standard form.

When setting up an aquarium for the Espei Rasbora (Lambchop Rasbora), a low water flow best suits their natural preferences. Because this species occupies the mid-level and surface zones, the aquarium layout should prioritise adequate surface area with floating cover to make them feel secure near the waterline and open swimming space in the centre of the tank for free movement. Useful additions include leaf litter or blackwater tannins to replicate their natural soft-water habitat and dense planting to provide cover, break sightlines, and reduce stress.

Classified as peaceful, the Espei Rasbora (Lambchop Rasbora) is a schooling species that feels most secure in a sizeable group, where natural shoaling behaviour reduces stress and brings out their best colours. When choosing tankmates, their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the mid-level and surface zones can help reduce competition and territorial overlap.
