Different Types of Ranchu Goldfish | Chinese Ranchu Explained

Choosing a Chinese Ranchu goldfish can be confusing, especially when you see so many different shapes, colors, and prices in fish stores.

In this video, I break down how to choose a proper Chinese Ranchu based on body structure, back curve, tail angle, swimming ability, and head growth (wen). These standards help you avoid bad purchases and find a Ranchu with real potential — even if you're not chasing competition-level fish.
In this video, you'll learn:
• The differences between Chinese, Japanese, and Thai Ranchu
• Why body structure matters more than color
