The Tairiku rose tanago is native to southern China, Taiwan, and the Korean Peninsula in East Asia and belongs to the family Carpidae of the order Carpidae, and is a river fish with bright rainbow body colors. It is also currently listed as an "Invasive Alien Species Requiring Attention" by the Ministry of the Environment. In this article, we would like to explain in detail the characteristics of the Tairiku Bara-Tanago and how to keep them.
What is a TAILIKU BARATANAGO?
The Tairiku rose tanago belongs to the family Carpidae of the order Carpidae. The origin of the Tairiku rose tanago is in East Asia: southern China, Taiwan, and the Korean Peninsula.The T. tairikubaratanago is tall and flattened. This gives it a diamond-shaped appearance when viewed from the side. The tairikubara tanago has a bright iridescent body color. The tairikubara tanago was introduced to Japan (Lake Biwa) in the 1940s. Later, it spread throughout the country due to freshwater shellfish aquaculture. The Tairiku Bara Tanago is in the same family as the Nippon Bara Tanago, which is native to Japan, and easily interbreeds, resulting in hybrid species. For this reason, it is now recognized as an "Invasive Alien Species Requiring Attention" by the Ministry of the Environment.

How to keep tairikubara tanago
Breeding of the T. tairikubara tanago is easy as long as you know how to keep them. The lifespan of the T. tairikubara tanago is approximately 5 to 8 years. Their body size is approximately 8 to 10 cm. However, both lifespan and body size vary depending on the environment in which they are kept and the food they are fed. They prefer slightly alkaline to neutral water quality, with a pH of 7.0 to 8.0. They can live in water temperatures between 5-25℃.

Points to keep in mind when mixing swimmers
Regarding mixed swimming, first of all, the character of the Tairiku Bara Tanago is mild-mannered. For this reason, many people mix them with killifish and goldfish.Be aware that the Nippon rose tango may become weak due to stress if the mixed species is a territorial species or a species that chases. Please make sure to check if they are eating the food properly when you feed them and if they are being chased.
Many people think that goldfish are the goldfish that you see at fairs and festivals in the summer, and that there are many different kinds of goldfish. And it is no exaggeration to say that each type of goldfish has its own characteristics, and that is the best part about goldfish [...]
When you go to a specialty store to look at killifish, you will be surprised at the many varieties available. The prices are different, as are the body colors and patterns, so it is hard to know what to choose. So, in this article, I would like to explain in detail about the different types of medaka.

Points about spawning
Many people who keep the T. tairikubara tanago want to breed them. In the wild, the tanago spawns in the spring. When kept in captivity, the signal for spawning is when the water temperature reaches around 20 degrees Celsius. When it is time to spawn, the male produces a rainbow nuptial color on its back. Females extend a black tube, called an oviduct, from near their rump.In some cases, the oviducts may be so long that they reach the tip of the tail fin.
Tanago lay their eggs on bivalves, whereas other ornamental fish such as killifish and goldfish lay their eggs on water plants. This spawning method is the biggest obstacle in trying to breed Tanago. This is because, unlike aquatic plants, you have to keep bivalves. If the bivalve that the bitterling spawned dies before the eggs hatch, the eggs will die with it. Another difficulty is that there are fewer specialty stores that deal in bivalves compared to aquatic plants. The types of bivalve mollusks used by bitterlings for spawning include the pine cone mussel, the dove mussel, the echinoderm oyster, and the mussel. If you are not sure, we recommend that you ask at a specialty store. If you want to breed bitterlings, the first step is to find bivalves.
When the bivalve is in the aquarium, the female lays her eggs in the gills of the shell using an egg tube. The male fertilizes the eggs by applying sperm to them immediately after the female lays them. The eggs hatch about 3-4 days after spawning, consume the yolk sac (nutrition received from the parents) in about a week, and grow to about 1 cm in about 20 days and emerge from the shell. At this time, the juvenile fish may have a shellfish baby attached to its fins. Just as the bitterling uses the shells, the shells use the bitterlings to expand their habitat. The male may protect the bivalves after laying eggs, but the fry are often eaten, so if you are keeping them in an aquarium, it is recommended to move the shells to another tank after confirming the spawning. Successful spawning of bitterling depends on how well you can keep the bivalves stable, so if you are worried about them or are not confident about handling them, we recommend that you purchase bivalves from a specialty store just before the bitterling spawns.
Points to keep in mind when keeping tairikubara tanago
The Tairiku Bara Tanago is a river fish with bright iridescent body colors. It is currently recognized as an "Invasive Alien Species Requiring Attention" by the Ministry of the Environment. Therefore, please note that the ecosystem may deteriorate if people who keep them release them into the wild.The iridescent nuptial coloration that the male T. tairikubara tanago produces during the breeding season is very beautiful. If you are interested in the Titanago, we recommend that you visit a specialty store to see them for yourself.
