Aquarium Setup for Medaka Gold Yozakura
Aquarium Filtration
Use a gentle sponge filter or a low-flow filtration system to maintain clean, oxygen-rich water. Avoid excessive currents and perform regular partial water changes.
Aquarium Plants
Live plants such as Java Moss, Hornwort and Water Sprite provide shelter and spawning surfaces. Floating plants also help create shaded areas and protect eggs.
Aquarium Lighting
Moderate lighting enhances the golden colouration and supports plant growth. Maintain a consistent photoperiod of approximately 8–10 hours daily.
Aquarium Heating
Gold Yozakura Medaka tolerate a broad temperature range and generally thrive around 18°C–25°C. A heater may be unnecessary in a stable indoor aquarium, depending on ambient conditions.
Aquarium Substrate
Fine sand or smooth gravel provides a natural-looking foundation. Bare-bottom aquariums are also suitable and make routine cleaning easier.
Aquarium Decorations
Incorporate smooth stones, driftwood and dense aquatic vegetation while preserving open swimming areas. Floating plants and fine-leaved vegetation provide useful cover and support natural spawning behaviour.
