Natural Habitat of the Hillstream Loach

Chinese butterfly loach inhabits deep rivers with a fast flow and upstreams highly saturated with oxygen, small tributaries of streams and rivers; zones restricted with crests and sometimes with waterfalls. in Jiangxi river system, the South of China, and the main branch of Zhu Jiang River.

This species was described in the upper part of Guizhou province, and it’s widely spread in the independent region Guangxi and Guangdong province.

In their natural environment, a Hillstream Loach will spend their time either working their way across the substrate looking for food or stationed out on a rock.

Their substrate is mainly sand, small rocks, round stones and gravel. In some instances, there is not even streamside vegetation. The water is crystal clear, with a small amount of dissolved oxygen.

Such sunlight and water conditions are right for biofilm development which consists of different types of algae and microorganisms. This biofilm covers all the rocks and stones surfaces like a blanket.

Sexing the Hillstream Loach

It is relatively easy to determine a male from a female Hillstream Loach.

The males have a stronger colouration and a smaller, slimmer body than the females.

Breeding the Hillstream Loach

Breeding hillstream loaches, although challenging, is possible. There have been no recorded successes in the home aquaria though.

You will need your water parameters and conditions to be perfect for this species to reproduce, and even then it could be unsuccessful.

You will know when your loaches are ready to reproduce because you will see the males displaying a mating dance to the females. If she is interested she will stay by his side instead of going about her usual business.

When the male has been given the green light, he will then build a nest by sorting through and digging the substrate, here the female will place her eggs, and the male will fertilise them.

The eggs will start hatching a couple of weeks after fertilisation, and there will be no need to remove the parents as they will not eat them.
