Calico Ranchu 12cm

Calico Ranchu

When it comes to the world of fancy goldfish there is an absolute sea of different variations to choose from. They range in colours, shapes, and sizes which often makes them lovely fish to keep in a dedicated display. One of these fantastic strains is the calico ranchu. Ranchus already would have to be one of the most popular goldfish because of their adorable stubby look and bubbly face. Calico ranchus carry all these loved traits and add a unique colour dynamic.

Calico Ranchu gets its name from the diverse variation of Dalmatian patterning and range of colours ranging from black, white, red, orange and blue. It is almost like these colours were just thrown onto the fish in random order and this randomness is present in every fish! To elevate this even further they have mirror-like scales scattered through the body that reflect light like a kaleidoscope. These fish have a comical round body shape with bubble growths on the face called a wen, overall these are just very adorable and odd-looking fish to keep.

Whilst goldfish are cold water tolerant and can be kept in outdoor ponds, it is better to keep ranchus indoors. These fish are not the best swimmers and are bred in tropical countries, they may not be able to hide swiftly from predators outdoors or even tolerate the near-freezing temperatures that comet goldfish can live in. Breeding these fish in captivity however is possible, sexing these goldfish is a difficult task but once males and females reach maturity they can show some chasing behaviours. Females may also appear to be larger when filled with eggs and have clear cheek plates whereas males tend to develop star-shaped bumps.

Tank Recommendations for your Calico Ranchu
The calico ranchu goldfish can get fairly big at 15 cm meaning that an individual would need around 100 litres but a larger aquarium is always better because what is better than one alico ranchu? Two calico ranchu of course!

The thing to note however with calico ranchu goldfish is that they are not the best swimmers so a slower flow is better. A sand substrate is best as ranchu will actively sift through the sand, smooth river stones can be added for further decoration. Sharp materials should be avoided in the aquarium like pointy driftwood as ranchu goldfish can easily get injured by them. These fish can tolerate plants to an extent as well, avoiding any fine-leaf plants would be best however a range of robust species can be considered like crypts.

Suitable Tank Buddies
Calico Ranchu are great fish as they are not aggressive in the slightest and can be kept with tank mates. Common tank mates they can be kept with are active and small cold water tolerant fish. The goldfish however might eat fry produced by these smaller fish however they will be perfectly fine with adults. Fin nipping species however should be avoided entirely as they will make short work of the slow-moving goldfish’s fins.

Feeding your Calico Ranchu
Feeding Calico Ranchu should be a breeze, they should immediately take to any aquarium food practically within 24 hours of being added to their new home. Having other ranchu as well will really cost their confidence making them an almost ravenous pack when feeding (all friendly though). Slow-sinking foods would be best as ranchu have been known to at times get swim bladder issues after frantically gulping for food at the surface. Good quality pellets or flakes that are rich in algae or spirulina content are best to suit their herbivorous diet.

Plant Safe?
No - however rough-leafed plants like Anubias may be okay.
