These adorable goldfish are not difficult to care for. However, note that Ranchu goldfish can grow large, up to 8”. So an adequate tank size is a must.
A Ranchu also has a longer lifespan than most pet fish. It can live up to 20 years if well looked after. Most Ranchu goldfish live for 10-15 years.
Now that you know you will live with your Ranchu for a long time, you must learn to care for your fish.
Here is a guideline to care for a Ranchu goldfish
Ranchu goldfish can get quite large. Therefore, you must get a tank that is big enough for your Ranchu.
It would be best if you did not keep your Ranchu in a fishbowl; it would not be enough for him.
Instead, get a large tank. If you plan on keeping more than one fish, go for a 20-gallon tank. A single Ranchu can do well in a smaller tank of up to 10 gallons. Though I personally prefer to house my Ranchu in a 20-gallon tank.
If you are thinking about keeping your Ranchu in a pond, this may not go well.
Ranchu goldfish do well in an aquarium in the home. They don’t usually fare well in a pond because they are a delicate species and don’t do well with a lot of extreme water temperature fluctuations.
They are also known to be slow swimmers which make them vulnerable to predators such as snakes and some birds.
Use gravel on the bottom of the tank and for aesthetic purposes, use silk plants in the aquarium and add some lighting in the aquarium.
Besides, adding live plants could encourage your Ranchu to uproot them. After all, the Ranchu goldfish is a digging fish.
Also, avoid putting anything sharp in the tank. Ranchu goldfish have poor eyesight and could run into sharp objects that would eventually hurt your fish.
What do Ranchu goldfish eat?
These adorable creatures are omnivorous. They will feed on algae, insects, and vegetables. You can also find fresh fish flakes for your little buddy. Other types of food that will be good for your Ranchu include:
- Brine Shrimps
While the Ranchu Goldfish enjoys foods rich in protein, only feed them moderately as some of these guys don’t know when to stop eating. Your Ranchu can get fatty which would affect his health and lifespan.
If you look closely, you will realize that Ranchu goldfish feed a bit slower than most fish. It is a result of their poor eyesight.
Note that when feeding plants and live insects, it could result in health issues. Live foods and plants may contain illness-causing parasites. So if you are going to feed it live food be sure to get it from a trusted source.
Good nutrition for a Ranchu goldfish will enhance their lifespan. Want your Ranchu to live longer? Only use good quality foods.
