67th "Blue Inveris" | Fish production is water production

Blue Inbellis flaring between males — Blue Inbellis flaring with each other while showing off their glittering body colors. This beautiful blue color was inherited from the Plakat, but the red of the tail and anal fins is the most distinctive feature of the Inveris. Based on the opening of the tail fin, it can be inferred that it is a half-moon plakat.

In the fall of 2019, I returned to Bangkok as usual and wandered around Chatuchak looking for any interesting fish-related stories.
When it comes to fish-related fish, it mainly involves betta fish, but in 2019, there were no notable new releases, and the betta fish industry was relatively calm.
That said, there are some small stories if you're looking for them, and I've introduced some of them in this column.
The fish I liked the most in the second half of 2019 was the Blue Inbellis, which I will introduce here.
Blue Inbellis itself was created several years ago and was introduced in this column in the 48th issue.
There are several reasons why I am bringing up a fish that I have previously introduced here again.
Let me explain it this time.

As I was checking out the shops on Beta Street in Chatuchak as usual, I was beckoned by the owner of Wild's shop.
When he removed the tank partition and shined a flashlight on the flaring fish, he found a beautiful Inveris.
It's also not the normal green color, but a shining blue fish all over.
I've heard about him breeding Blue Inbellis for a while now, and it looks like he's finally able to release it.
There were about 10 males lined up in the shop, and although they are still small, their colors are perfect.
I asked if they also have females, and they said they can be sold in pairs, and the price is reasonable.
Previously, when Blue Inveris first appeared on the market, the price was quite high and I was a little hesitant to buy it.
So, personally, I'm very grateful that this pair is reasonably priced.
When photographing a new variety, the aim is to photograph as many individuals as possible as models in order to confirm its completeness.
Photography is also a job, so there are limits to how much you can spend on it.
Blue Inbellis were expensive when they first appeared, and you could barely get one male.

The shade of blue varies depending on the degree of excitement of the fish. Perhaps because it has Plakat blood in it, it does flaring more often than normal Inveris. The size of the fish is similar to normal Inveris, slightly smaller and slimmer. I want to keep the red color of the tail and anal fins and the body shape the same as the original, even if Splendens blood is mixed in.

Almost all males display the same beautiful coloration. — The quality of this Blue Inbellis variety is extremely high, and almost all males display the same beautiful coloration. However, if selective breeding is carried out, it seems possible to produce solid blue fish. In that case, the only difference from the plastic cut would be the body shape.

When photographing betta fish, I am particular about photographing flaring between males of the same species or breed as much as possible.
It is very helpful to be able to select a model from among many individuals at an affordable price like this time.
Remove the partition from the aquarium and choose the one you like for its color and body shape from among the flaring males.
In terms of color, they are all similar, almost like Kintaro candy, but there are individual differences in the length of the fins, so select one that is well-elongated and has no peculiarities.
Now, after I finished selecting the fish, I asked the shop owner again about the history behind the creation of Blue Inveris.
The fish were not purchased from other sources, but were bred by him himself, so I was very grateful to be able to hear about them directly.
Information that you hear through someone else is bound to have many mistakes and cannot be completely trusted.
This is especially true when converting from Thai to English and into Japanese.

A female exhibiting an intense blue color. — A female exhibiting a deep blue nervous color. Looking at this color, it is obvious that it is of the same lineage as the male. Although she is a young and small female, her abdominal ovaries have already developed and she is capable of breeding.

The Blue Inbellis was apparently created by breeding a male Inbellis from Krabi with a female Plakat, known in Thai as Swee Namgoong (dark blue).
It is not a pure Inveris, but the color has been transferred from plastic cut, and it seems that it took about three generations to select individuals that showed strong Inveris characteristics.
If you look at the photos I'm introducing this time, you'll probably agree, but I can say that her body type is almost 100% Inveris.
The red coloring of the tail and anal fins, which is the most distinctive feature of Inveris, is almost perfect.
If I didn't hear that they introduced the Plakat bloodline this time, I would definitely believe them if they told me they were pure Inveris.
I have always felt that Thai breeders do not keep secrets or lie when asked for information about these matings.
They probably have confidence and pride in their technology.
Recently, there have been cases where Plakat bloodlines have been introduced to improve wild betta fish.
is increasing.

Even under normal conditions, a faint blue color appears on the gill covers and sides of the body. — A different female from the previous photo. Even in normal times, a faint blue color appears on the gill covers and sides of the body. This individual has already developed ovaries and can be used for breeding immediately. Distinguishing the sexes of the Splendens group is easy by looking at the body color and length of the fins, but the female characteristic is the white protrusion near the reproductive opening, so it's easy to tell if you pay attention to this.

The Yellow Inbellis and Yellow Splendens, which have been introduced in this column, are also fish created through similar crossbreeding.
Few people may remember that several decades ago, Kenjiro Tanaka of the Tropical Oviparous Medaka Research Institute in Osaka used the same method to create all-blue inbellis.
I remember being a student and not being able to buy one because I didn't have the money, but still dreaming of it.
The only people who can understand this story are serious maniacs who are around 50 or older (lol)
A breeder who bred a strain of Inveris called Penang Green on Penang Island in Malaysia about 20 years ago also said that he had crossed Splendens a long time ago.
When I heard this, I thought that Splendens and Inveris might have been interbred without my knowledge.
The female Blue Inveris also has a strong blue body color, so you can be sure that it is a female of the same strain.
Normal female Inveris have a plain body color, but this female Blue Inveris is quite colorful.
I can feel the crossbreeding with Plakat around here.

If you look at this photo, you will understand the high level of perfection of Blue Inveris.
If you like wild betta fish, you will definitely want to keep them.
In 2020, I hope that it will become popular among wild enthusiasts in Japan.
