关于青兰寿

Blue Ranchu is a ranchu-type goldfish with a muted blue-gray hue inherited from the Blue Wenyu. Its dorsal-fin-less rounded body and shifting coloration make it a distinctive, intermediate-level variety that grows to about 15 cm.

迎接青兰寿前需要了解的7件事

1. 1No Dorsal Fin, Slower Swimmer

   Blue Ranchu have a rounded body without a dorsal fin, which makes them slower and less agile swimmers than other goldfish. Strong currents and tanks with steps or ledges can be stressful, so aim for a calm, gentle environment.

2. 2Color Fades With Age

   The muted blue-gray inherited from the Blue Wenyu often fades toward white as the fish matures. This is a natural change rather than a sign of illness, so there's no need to worry if the color lightens over time.

3. 3Stable Water Quality Matters

   The ranchu body shape is sensitive to shifts in water quality, so regular water changes and reliable filtration are essential. This is part of why the variety is considered better suited to keepers with some prior experience.

4. 4Choose Tankmates Carefully

   Because they aren't strong swimmers, Blue Ranchu can struggle to compete for food or get their fins nipped when kept with faster or more aggressive goldfish. Pairing them with similarly slow-swimming varieties tends to work best.

5. 5Keep the Tank Layout Simple

   Sharp ornaments or tight gaps in the decor can cause bumps or getting stuck, since the body lacks a dorsal fin for fine control. Choose rounded decorations and leave plenty of open swimming space.

6. 6Change Water Temperature Gradually

   As with goldfish in general, sudden temperature swings can cause stress or health problems. Match the temperature during water changes and ease the fish through seasonal shifts slowly.

7. 7Prepare the Tank Before Arrival

   Cycling the filter before introducing the fish helps keep water quality stable from day one. Acclimate the fish gradually to the new water's temperature and chemistry before releasing it into the tank.
