Introduction

Lambchop Rasboras are captivating fish known for their vibrant red or orange bodies adorned with a distinctive black or dark purple mark on their sides, resembling a lambchop. This unique pattern, along with their peaceful nature, makes them a popular choice for community aquariums. They are particularly striking against dark-colored substrates, which highlight their bold colors.

Physical Characteristics

Lambchop Rasboras have bright red or orange bodies with a distinctive black or dark purple lambchop-shaped mark on their sides. Males tend to be more colorful with more pointed lambchop markings, while females are rounder with more rounded markings. Their small size, typically 1 - 1.5 inches, makes them ideal for nano tanks.

Behavior and Compatibility

These fish are peaceful and thrive in schools, making them ideal for community tanks. They are compatible with other non-aggressive species, as well as snails, shrimp, and live plants. Keeping them in groups of 6 or more reduces shyness and promotes natural behavior.

Diet and Feeding

Lambchop Rasboras are omnivorous and not picky eaters. They will readily accept flake foods, pellets, and algae wafers. To enhance their colors and encourage breeding, their diet should be supplemented with frozen or live foods such as brine shrimp, bloodworms, daphnia, and insect larvae. They also enjoy blanched vegetables like lettuce, zucchini, and kale.

Tank Setup and Care

• Tank Size: A minimum of 10 gallons is recommended.
• Water Conditions: They prefer temperatures between 72° - 79° F (22° - 26° C) and a pH range of 6.0 - 7.0. The recommended KH range is 2 - 10 dKH.
• Aquarium Decor: Provide plenty of plants, rocks, and driftwood for cover. These elements mimic their natural habitat and make them feel secure.
• Social Behavior: These schooling fish do best in groups and will school with other rasboras and danios.

Breeding

Lambchop Rasboras can spawn in a well-maintained, densely planted aquarium. Males display brighter colors and court females by performing a dance. Fry may appear if conditions are optimal and the tank is well-cycled. Ensure a varied diet to encourage breeding.
