🌿 Overview

The Emerald Dwarf Rasbora (Microdevario kubotai) is a breathtaking nano fish celebrated for its vivid emerald-green coloration and peaceful social behavior. Originating from clear forest streams in Thailand and Myanmar, this species adds both movement and a splash of color to any planted aquarium.

Small in size but rich in personality, these rasboras are best kept in groups of eight or more, where their natural schooling behavior can be observed. They are ideal for beginner aquarists looking for an easy yet visually striking fish species.

🧠 Behavior & Compatibility

Emerald Dwarf Rasboras are non-aggressive, making them compatible with other peaceful nano fish, shrimp, and snails. Their gentle nature allows them to coexist beautifully in community aquariums alongside species like Neon Tetras, Harlequin Rasboras, and small Corydoras.

🧴 Tank Requirements

These fish thrive in well-planted aquariums with plenty of open swimming space and gentle filtration. Floating plants help diffuse light, replicating their natural environment and encouraging vibrant coloration. Regular water changes (around 25% weekly) are essential for maintaining their health.

🍽️ Feeding

Emerald Dwarf Rasboras are omnivorous and will readily accept high-quality micro pellets, crushed flakes, and frozen or live foods such as daphnia, brine shrimp, and microworms. Offering a variety of foods helps maintain their color and vitality.

💧 Water Parameters

Keep the aquarium water soft to moderately hard and slightly acidic to neutral. A consistent temperature between 22–28°C (72–82°F) and stable water conditions are vital to their well-being.
