What Are The Types Of Freshwater Fishes?
The only two types of freshwater aquarium fish in Japan are the dwarf barbel and the catfish. The dwarf barbel is still very small compared to other tropical fishes. You should keep them as pets, but it does not seem possible for most people in Japan to afford pet fish.
The Catfish is a normal-sized fish that is very similar to Koi Fish. It is very active. Therefore, care should be taken to make sure that they get enough exercise. There are some freshwater fishes from North America that are larger than Japanese freshwater fishes. The Black Carp, the Dogtooth, and the Betta in particular can be problematic.

Red Tail Sharpies is another variety of freshwater fish that can be found on eBay. They are not hardy and cannot survive in a freshwater aquarium.

Few Things You Should Know Before Keeping Freshwater Fishes In Japan
To keep freshwater aquarium fish in Japan, you need a good quality aquarium filter and heater. You can get these at your local pet store or on eBay. It is very important to have the right size of tank for your fish.
A good thumb rule is that the bigger the tank, the better. If you put your fish in a smaller tank, they will get stressed and won’t survive. It is important to put the right type of food in the tank and change the water weekly. It is recommended to leave the tank in a dark room during the day.
