Redtail Glassfish (Prionobrama filigera)

【Adult size】Around 5 cm
【Water temperature】18-24℃
【Food】Flake food, bloodworms, brine shrimp

When the Rosy Red Minnow swims in the water, its brilliant red tail is particularly striking. If you observe the internal organs and bones of the Rosy Red Minnow closely, you will find a thin blood vessel that runs from its head all the way to the tip of its tail. Surrounding this blood vessel are even finer, comb-like fish bones, which constitute the Rosy Red Minnow's skeleton. Its abdomen contains an oval, opaque (or semi-transparent) internal organ that emits a faint green fluorescence, and its intestines are intricately and regularly coiled within this oval structure.
