Lambchop Rasbora (Trigonostigma espei) – Aquatic Arts
This beautifully-marked, peaceful species is a variant to one of the most widespread and longest kept species in the aquarium hobby!
Lambchop Rasboras make an absolutely captivating addition to any aquarium. Their bodies are mostly a bright red or orange color, but they are named for the black or dark purple mark on their sides that resembles a lambchop in its shape. The combination of these bold colors really makes these fish stand out from all others, especially when they are paired with dark-colored substrate.
Males tend to be more colorful than the females, and their lambchop markings are usually more pointed in appearance. The females are often rounder in shape, and their lambchop markings are more rounded as well. Their diminutive size makes these fish great for small community tanks.

These fish are vibrant and peaceful. I added them to my 10-gallon tank with neon tetras and they blend well. The red and black markings stand out especially in dark gravel. They swim together in small groups and don’t stress other fish.

Great little fish with a unique look. The lambchop marking is very noticeable. I noticed the males are more vivid than females. They’re easy to care for and stay active in the tank.

I’ve had these for three months and they’re still healthy and active. They pair well with other small rasboras and don’t fight. The color contrast is striking in my dark tank setup.
