Espei Rasbora (Trigonostigma espei) Care Guide:
The Espei Rasbora, also known as the Lambchop Rasbora, is a peaceful and vibrant schooling fish ideal for community aquariums. Native to the slow-moving, plant-rich waters of Thailand and Cambodia, it thrives in groups of six or more in a well-planted tank with open swimming areas. These small, copper-orange fish prefer warm, soft, slightly acidic water with temperatures between 75–82°F (24–28°C) and pH 6.0–7.5. They reach about 1.5 inches in length and are best kept in a minimum 15-gallon aquarium. Espei Rasboras are omnivores, enjoying a varied diet of high-quality flakes, micro pellets, and live or frozen foods like daphnia and brine shrimp. Peaceful and active, they make excellent tankmates for similarly gentle fish such as tetras, gouramis, and small catfish.
