About

Basic blue and white refer to the most fundamental and popular medaka body colors. Blue medaka shows a deep, calm blue from the balance of black and yellow pigment cells, while white medaka has reduced black and yellow pigment for a cream-tinted white. Both are foundational colors from which countless improved varieties were developed; they are hardy, easy to keep, and ideal for beginners. Standard body type, roughly 3–4 cm. Adaptable across a wide 5–30°C range in neutral to slightly alkaline water, thriving in everything from outdoor biotopes to indoor tanks, and easy to breed. Blue shows best in dark containers and white in bright ones. Peaceful in temperament and suitable for community tanks with similar-sized gentle varieties — a classic first choice for those starting with medaka.
