The Black Kuhli Loach, Pangio oblonga, is a detailed relative of the Kuhi loach, Pangio kuhlii, however just isn’t as well-liked in aquariums due to its plainer colouring. The Black Kuhli loach comes from India, Bangladesh, Myanmar, Cambodia, Laos, Vietnam, Thailand, Indonesia and Malaysia.
The utmost size of this fish is about 8 centimetres (3 inches), however as a result of it’s a skinny eel like form, that is nonetheless a small fish.
This can be a tropical fish and a temperature of between 23 and 28 levels C (between 73 and 82 levels F) is appropriate. This fish comes from gentle acid water and the normally beneficial circumstances for them in an aquarium are a pH of between 6.2 and seven.2, with gentle water. Though it appears logical to method the water parameters of its pure habitat, Richard Bias of New Jersey, USA has saved and bred this fish with a pH of 8.0 and comparatively laborious water with a gH of 18-22 and a kH of about 20.
It could be that conserving the water clear and with constant pH and hardness is extra necessary than the precise values of the parameters.
Within the wild their habitats typically have a sandy backside. That is typically beneficial for aquariums, however Mr. Bias used small rocks of as much as 2.5 cm (1 inch in diameter). I’ve additionally had success with conserving this species utilizing a substrate of small pebbles.
Within the wild they’re used to crops and an aquarium ought to have loads of stay crops.
Black Kuhli Loaches are omnivores, however their weight-reduction plan requires an affordable quantity of animal primarily based meals. My Kuhlis appear to notably like frozen blood worms (so do many fish). I additionally give them frozen brine shrimp as soon as every week. They may also eat regular fish meals like flakes.
They’re backside feeders and solely eat what falls to the underside.
Black Kuhlis are partially nocturnal. Mixed with this they are going to burrow into the substrate and are good at hiding within the crops, so you might not see them a lot. They’re troublesome to catch.
Though they can’t be described as a education fish, they appear to do higher in teams; the bigger the higher.
They’re peaceable fish and could be saved with different small peaceable fish. They’re an excellent inhabitant for a properly planted neighborhood tank of at the very least 50 litres (13 US gallons).
When in breeding situation the females turn out to be distinctly fatter than the males.
Breeding within the Wild
It’s believed that within the wild this fish breeds in flooded forests. The forest ground might properly have a lot natural particles from the timber and the newborn loaches in all probability develop amongst these; feeding on the wealthy animal and vegetable meals which grows on this surroundings.
Breeding in an Aquarium
I counsel that two probably necessities for fulfillment are wonderful feeding together with wealthy meals like blood worms, and a substrate that may enable the infants to stay and feed in.
Though the identified single instance of profitable breeding in aquariums just isn’t sufficient to make agency conclusions, it means that breeding in a neighborhood tank just isn’t unattainable.
Within the wild this fish just isn’t threatened and appears to have the ability to reproduce itself very properly. I counsel that the rarity of breeding success in aquariums could possibly be because of the probability of the circumstances within the wild that stimulate breeding being fairly completely different from people who the adults usually stay in.
