80th Red Eye Plastic Cut “2020” | Fish production is water production

Red-eyed plastic cut with flaring between males. Their bodies are not thin and sturdy, and their eyesight is fine, so they spread their fins wide in response to other fish. Individuals like this are extremely valuable.

In the past, this column has introduced red-eyed betta fish by calling them albino fish. However, as I have seen many red-eyed betta fish with my own eyes, and have heard information from breeders in Thailand and Japanese fish enthusiasts, I feel that it is not appropriate to call a fish with this phenotype an albino. I came.

In fact, in Thailand, the home of the betta fish, breeders do not call this fish an albino, but a tarden. In Thai, ta means eye and den means red. Learning from this name, I would like to refer to these red-eyed bettas as red eyes here. It seems that many Thai breeders have bred this Redeye in an attempt to fix it, but as far as I know, I have never heard of anyone being able to fix it.

An extremely rare Galaxy Red Eye individual. He seemed to have no problems with his eyesight and actively flared to show off his attractive colors.

A male Nemo betta red eye. Although it has a sturdy body, it seems to have poor eyesight, and although it could spread its fins, it did not flare with other individuals. Unfortunately, these individuals cannot be used for breeding.

First, I'll write down as much information as I know about this Red Eye. There are two types of red-eyed individuals: individuals with red eyes in both their left and right eyes, and so-called odd-eyed individuals with only one red eye. Many red-eyed fish tend to have poor eyesight, so it seems that few individuals with red-eyed eyes grow up to adulthood, either because they don't get enough food to grow, or because they have a weak constitution to begin with. As a result, individuals with red eyes in both eyes are quite rare, and individuals with sufficient eyesight are even rarer. On the other hand, individuals with red eyes in one eye seem to have a higher probability of growing up to adulthood, perhaps because the vision in one eye is fully functional, and they are more likely to be seen than those with red eyes in both eyes.

A red-eyed individual with a slender and weak appearance. Although it seemed to be able to see other individuals and reacted, it did not actively flare. In the case of individuals like this, it is extremely difficult to take photos with their fins spread out.

The visual acuity of these redeyes varies considerably from individual to individual, with some individuals being able to flare like normal fish, while others are unresponsive to food or other fish. Many fish have red eyes in both eyes but only have vision in one side, and when you show them other fish, you can tell by their reactions. In the case of betta fish, many breeders separate them into bottles after they grow to a certain size, which is why even individuals with poor eyesight can grow them.

Although he is young, this male red-eyed Koi betta has a sturdy body, and his fins are fully extended and flaring. It is unclear whether it is because they are produced in large numbers or if they tend to appear systematically, but there are many opportunities to see the red eyes of Koi betta and Nimo betta.

Although it is a slightly older individual, this male red-eyed Nemo betta has good eyesight and spreads its fins towards other individuals. These red eyes are often found mixed in with regular Nemo bettas, and this is where your discerning eye is put to the test, and finding one is very satisfying.

Even individuals with relatively poor eyesight can eat food in a narrow bottle if the food hits the tip of their snout. However, even if they were to breed, it would be impossible to find females without eyesight, and it would be impossible to care for eggs and fry in the first place. Redeyes are originally rare, but some of them have good eyesight and there are a few individuals that blow bubble nests during the breeding season. There are very few male Red Eyes that have good eyesight and are physically capable of breeding, so they don't appear to be commonly available. I have heard of the results of breeding using these individuals, but it seems that even if red eyes are used for both males and females, the offspring will not have red eyes. I have also heard reports that even if you use Red Eye for one parent and cross the F1s with each other, Red Eye will not appear. Apparently, Mendel's laws do not apply at all when it comes to the inheritance of red eyes. Unfortunately, because of these difficult problems, the Red Eye Betta has not yet been established as a breed. Since I don't have a deep knowledge of genetics, and I don't know much about the genetics of betta fish, it's impossible for me to come up with a correct answer regarding the genetics of this red-eyed betta fish.

A male red-eyed Nemo betta with a normal body shape and not at all skinny. My eyesight is fine and I am doing flaring. It would be a good idea to select those that create bubble nests from among these healthy redeye individuals and use them for breeding.

It seems that his eyesight is a bit weak and he didn't flare with other fish, but he is a male red-eyed carp betta with a very good body shape.

However, as a result of having seen many red-eye bettas, I have my opinion as an amateur. Redeye bettas do not appear to lack pigment in any areas other than the eyes, unlike other albino fish. It appears that their red eyes are simply due to a lack of the black pigment in their eyes. Isn't this a phenomenon that could be called partial albino? If we can elucidate the genetics that causes a deficiency in only the black pigment in the eyes, wouldn't it be possible to fix red eyes as well? In fact, multiple of them may appear at the same time on the same farm, like the Blue Rim introduced in the 79th article of this column. This time, we would like to introduce beautiful individuals selected from among the redeyes found in Thailand during the six months from spring to fall of 2020. I would also like to see a true albino betta that lacks not only eye pigment but also other pigments.
