61st “Yellow Inveris” | Fish production is water production

A steel blue type of Yellow Inveris that spreads fins between males. Its slender body shape is similar to that of Inbelis, and its distinctive features are the edges of its caudal fin and the rear end of its anal fin, where the red has been replaced with yellow. This is an individual likely to be liked by wild betta lovers.

It's already on sale in Japan, so many people may have picked it up, but it's been a while since I've produced a large book related to Betta.
The book titled Betta2020 introduces XNUMX improved breeds of Betta in full color.
The title of the book is based on the upcoming Tokyo Olympics 2020.
Of course, for those who like wild betta fish, we also introduce many original betta species of the Splendens group, as well as their regional variations and hybrids.
This is a must-have book for betta lovers, so I hope many people will read it.
So, that's enough about promoting the book, let's get to the main topic.

A male steel blue type yellow inbellis. In this individual, slightly red chromatophores can be seen remaining in the yellow parts of the caudal and pelvic fins. It can be said that this is an individual that you do not want to select as a parent when maintaining a lineage.

This book was co-authored with Takashi Omika, who is also active in Aqualife magazine, and took a considerable amount of time and effort to produce.
So, let's celebrate the completion in Bangkok! That's what I decided to say.
In April, the hottest month in Thailand, Mr. Omika came to visit me as I had arrived in Bangkok first.
However, neither of us has the personality to just complete the book launch in Bangkok.
Naturally, both of them end up looking for new models and taking photos in preparation for their next book.
Is this a habit of poor freelancers?
So, whenever I had time, I wandered around the Sunday market in the intense heat, looking for model bettas.

Also, the way Blue rides varies greatly depending on the individual. The selection of females is also important when maintaining the lineage, so it is important to select them as carefully as males.

A female Yellow Inveris. Like males, females seem to have lost their red pigment, but the blue pigment on the sides of their bodies remains.

When I went to my usual little-known shop, I saw an unfamiliar fish in a hard-to-see place at the top of the shelf!
When I pulled out the case divider, a new fish started flaring, although it looked like I had seen it before.
Its body shape is exactly like that of Inveris, but the characteristic red color of its tail and anal fins is missing.
The parts that are normally red have been replaced with yellow.
When I asked the shop owner, he said it was Yellow Inveris. It seems to be a new variety that is original to this store. I felt that regular checks were essential for this store.
In Japan, these new fish would probably be given some kind of pop to make them stand out.
However, here in Thailand, there is no such appeal. You need to use your own eyes to find new varieties.
For this reason, connoisseurs are in high demand. Only those with a discerning eye can catch good fish faster than others.

A male individual of the blue-green type of Yellow Inbellis with a body color that has a glittering metallic luster. This individual has an Inbelis-like body shape, and the yellow color on the tail and anal fins is perfect. I would love to pass on this color to the next generation.

This Yellow Inbellis is not flashy, but it has something very appealing to wild betta lovers.
When we asked the price, it wasn't so expensive that we couldn't afford it, so naturally we both immediately bought two of them.
Only males were for sale, so I asked if they had any females, and they told me they were at the farm and they would bring them in the next week.
After all, you will want to collect a pair of these betta fish and try to breed them.
The male I obtained at this time had a steel blue body color, so I assumed that it was bred from the Steel Blue Inveris, which I previously introduced in this column.
The next week, when I went to the Sunday market to pick up the scalpel, I learned that the shop had another branch.
When I looked into that store, in addition to the Steel Blue Yellow Inveris that I saw the previous week, there were also individuals with blue-green and blue bodies.
My Thai buddy was with me this time, so I asked him a lot of questions about this fish.
Then, it turned out that this Yellow Inveris was not a pure strain, but was created through crossbreeding with Splendens mustard gas.
Mustard gas is a variety with beautiful blue and yellow colors, and is characterized by the fact that it does not contain any red pigment.
Even so, it is surprising to the sensibilities of Thai breeders that they removed Inveris' characteristic red pigment and turned it yellow.
This is an idea that would never occur to Japanese people.

So, I ended up purchasing the blue-green and blue Yellow Inveris that were lined up at the store for photography purposes.
Personally, I liked the steel blue type that I first purchased because it was the most Inverith-like.
If you have a type that has a lot of blue on the sides of your body, it is likely that you will end up with a plastic cut if you get thicker.
In this case, it is unclear how much improvement can be made.

A male Yellow Inbellis whose body is covered in metallic blue. Unfortunately, the width of the yellow tail fin, which is a characteristic of this breed, is somewhat narrow. Although it is beautiful in color, the wildness of Inveris is no longer felt, and it can be said that it is an individual that has different tastes depending on the person.

A male Blue-type Yellow Inveris competing with the Blue-Green type in the back. The ground color on the side of the body can also be seen to be yellowish. The characteristic yellow color of the tail and anal fins is also distinct, giving it a calm beauty.

The most distinctive feature of this breed is the yellow border of the caudal fin and the rear end of the anal fin.
This is noticeable in steel blue and blue green, but I have also seen some individuals with blue types that are not very clear.
We also observed individuals with a slight amount of red pigment remaining in this yellow area.
This breed maintains the slender body of Invelis, retains the deep yellow color of the caudal and anal fins, and has a wilder coloration on the side of the body, which seems to be the perfect form.
It's a beautiful and attractive variety, so I'm sure we'll see more of it in Japan from now on.
I would like the ornamental fish industry to introduce these types of fish, not just the latest trends.

Finally, I heard some good news for betta fish lovers, so I would like to report it.
In Thailand, there was a debate about whether or not to designate the betta fish as the country's national fish, but the government recently approved the idea, and the fish became the ``national fish of Thailand.''
When it comes to betta fish, Thailand is definitely the best, so I hope that they will continue to lead the betta scene.
