Interesting Facts About Soragoi Koi Fish

History of Soragoi Koi 

The Soragoi are a type of Ogon group of koi, which first appeared in the Showa Period (1926-1989). This is a name derived from the Japanese words "sora" and "ogon," meaning "sky" and "Tail".

They come in different color varieties including pale ultramarine and deep sky-blue colors. The scale edges on Soragoi are more prominent than those on the Chagoi. There may be a little bit of shine (Hikari) on top of the head, but the fins are not as bright.

Ogon was formed from Kin Kubuto, which was derived from Chagoi in order for Soragoi, which is an offshoot from Ogon, to have Chagoi as its forefather; therefore we may describe the two as closely related.

Tips for Finding Perfect Soragoi Koi 

Although many individuals believe that finding a high-quality Soragoi koi fish is simple because they are only a single color, this isn't always the case. In reality, finding an excellent Soragoi koi can be quite tough.

Because this fish has no vibrant pattern, you'll want to pay close attention to the formation of the fish's scales. Look for a reticulated pattern and be cautious of any missing scales, which will disrupt the scale's pattern. Additionally, as your Soragoi matures, missing scales will only become more of an eyesore.

If you want a high-quality Soragoi that meets all of the requirements of the breed, you'll likely have to pay a bit more. However, the extra money will be well worth it when you see your beautiful koi fish swimming in your pond.

When shopping for Soragoi koi, it is important to find a reputable dealer. This will ensure that you are getting healthy fish that meet the standards of the Soragoi breed. A healthy and safe Soragoi fish will make a perfect addition to your pond or aquarium.

Chagoi and Soragoi are two distinct types of koi. Chagoi was developed in the Taisho Era, whereas Soragoi did not appear until the Showa period. The two are, however, closely related.

What Happens if You Overfeed Soragoi Koi? 

Some people may believe that fish require more feedings since they are constantly on the lookout for food sources. Fish will, however, act as if they are hungry at all times, which might be mistaken for them not being full when in fact they could be eating too much.

Overfeeding may reduce the quality of life for your fish, causing their bodies to develop fat deposits, which can have a negative influence on their health. This is why you must be cautious and feed your fish only in the correct quantities.

In addition to overfeeding, there's also the issue of underfeeding. However, we believe that fish are better off being underfed than overfed since you may determine the right proportion of food for your fish.
