When I went to Seoul this week to view the display of native Korean fish in aquariums, several species caught my eye as having potential in the global aquarium market.
Among them were the dozen or so species of elongated loaches. Most of them have beautiful markings but otherwise unremarkable colors. The two members of the genus Koreocobitis, however, sported eye-catching blotches of red of varying intensity.
In the first two photos are K. rotundicaudata showing color variation over a different substrate. The third picture is of K. naktongensis. These two fish are very closely related and until recently, were classified as the same species. However, the spotted white-nosed form inhabits only the southern Nakdong River in South Korea while the more common white-nosed version inhabits a broader ranger in the northern half of South Korea.
Wanna know more about other loaches?
They are long fish and a group of them should be housed in a fifty gallon/ 180-liter tank. Because they inhabit just the lower portion of the tank, you could house them with any midwater fish that like flowing water and can tolerate room temperatures.
They are found in Endemic to South Korea waters. You can Found them there.
They can grow Up to 18cm / 8 inches if they are cured and cared properly in an effective way.
No heater is needed. No, any temperature range is specified so you can keep them in room temperature or normal water temperature. It’s easy to keep them in the aquarium.
They adapt readily to sinking, prepared foods but should be given regular feedings of live or frozen foods such as bloodworms.
It is likely that these cousins can interbreed as their differences were caused by geological separation. They are called white-nosed loaches, despite clearly not having white noses, because of the light band that extends across the top of their heads nearly to the tip of their noses. They lay eggs in the substrate under stones. In nature, breeding in May and June.
Their tank should contain many stones and a substrate of sand or gravel. Take four smaller stones and arrange them so a large, flat stone can be laid atop them like a table. Secure the stone with aquarium safe sealer so it cannot shift and injure the fish.
The opening to beneath the stone should be only slightly higher than the height of the loach. They will spend most of their time underneath this structure and may even breed there.
The water should be well filtered with a good flow of water and extra oxygen added to the tank via an airstone. Be sure to cover the intake valve of the filter with a sponge or fine nylon mesh as. From a stocking. These Loaches have a tendency to enter the filter pipes.
