Hillstream loach tank Size, Temperature, Care, Breeding | Hillstream loach vs Butterfly loach

Fish and other aquatic organisms can thrive in a variety of environments as long as they are habitable. Being a hobby aquarist means that the creatures you chose for your tank will be easy to care for and will thrive if you supply them with the proper tank conditions.

The hillstream loach requires modest care, making it suitable for both expert and inexperienced aquarists. Hillstream loaches are found in Asia's tropical regions, where they live in fast-flowing streams. Additionally, they exist throughout China and the Indian subcontinent. They are mainly restricted to fast-moving mountain streams with strong currents in this region.


    Their preference for fast-moving waters is the fundamental cause of their distinct look. Due to the fish's low hydrodynamic drag, they can endure strong currents found in their natural environments without being swept away like other species.

    Most hillstream loaches spend their time behind rocks or quietly searching the riverbeds for food in their natural environments. They can also glide over smooth stones and ascend overhanging and vertical surfaces in rivers more easily than other fish species.

    It is vital to have a comprehensive understanding of the contents of their native habitats in order to create the same in your aquarium so that the fish are comfortable.

    Hillstream loach tank Size

    Hillstream loaches reach a maximum size of 2-3 inches in length. The fish can easily hide in nooks and rocks due to their small size. A tank with a minimum capacity of 30 gallons is appropriate for your hillstream loach.

    Because the fish must be kept in groups of 3 - 4 to survive, this is the case. Furthermore, the fish cannot be kept in tiny tanks because of their optimal water flow and oxygen requirements. When hosting hillstream loaches, you'll also need to meet the following conditions for your fish tank:

    • Filtration canisters should be mounted externally
    • Additional powerheads are required to ensure appropriate water flow and a sufficient supply of oxygen.
    • For the tank's substrate, use fine gravel and sand. Because most loaches swim at the tank's bottom, abrasive sand might injure their smooth bodies.
    • Algae development can be enhanced by the use of bright lights. There should be a minimum of four 40-watt bulbs in this arrangement.
    • There should be plenty of hiding places in the driftwood and sturdy plants.

    Hillstream loach tank Temperature

    To achieve the right base water conditions for your hillstream loach, it's a simple process. The following are the suggested water conditions for your fish:

    • PH range: 6.5-7.5
    • The temperature range should be between 68 to 75 degrees Fahrenheit (20 to 26 degrees Celsius).
    • The hardness of water: 10-15dKH
    • Regular water testing using the appropriate kits would be beneficial in ensuring that the following criteria are maintained in your tank. Though hillstream loaches are resilient species, they will be harmed by parameters that are too far from the ideal.
    • In their natural environments, loaches are utilized to purify water. It is recommended that you perform at least a 30% water change every week to maintain the tank's water quality.

    Hillstream loach tank Care

    The hillstream loach, like all loaches, is omnivorous. Its preferred food is algae, which grows on the rocks in your aquarium. The algae will be consumed by the fish on a regular basis.

    As a result, it should be regarded as the topping on the cake rather than the main course of your loach's diet. While you should have the proper atmosphere in your aquarium to encourage algae growth, you should not have too much of it.

    Consider having two tanks so that you may transfer the loach to one and allow the other to accumulate enough algae before returning them.

    If you want your hillstream loach to have a healthy diet, feed them frozen bloodworm larvae, flake, pellets, brine shrimp, and algae wafers.

    You may also add blanched spinach and kale, as well as courgettes and cucumbers, to give them extra nutrition and vitamins. Assure that the pellets and flakes you provide your loach are not too large due to the fish's smallmouth.

    Hillstream loaches should be fed in little amounts because large amounts can be lethal. This is due to the fact that they are habitual to scavenging in the wild and only eat when food is available.

    It is sufficient to feed the loaches once or twice a day. When they are first introduced to your aquarium, some may refuse food for a few days due to the new surroundings. Regardless, they will feed on the algae in your fish tank.

    Hillstream loach Breeding

    Hillstream loaches can live for 8-10 years in a fish aquarium if properly cared for. Though breeding loaches in your aquarium can be difficult, it is doable with the appropriate water conditions.

    To reduce the chance of other fish species feeding on the eggs and fry of the hillstream loach, keep your tank entirely for loaches. So get a new breeding tank.

    Males initially pursue females by performing a mating dance. Following mating, the male excavates a nest in the substrate, which the female uses to lay her eggs.

    Males can readily discover nooks and crevices to create nests in rounded river gravel, which makes it a perfect substrate for breeding tanks. The eggs will hatch in two weeks after they have been fertilized. The adult hillstream loaches will not kill their fry, therefore you don't need to separate the hatched eggs from the adults.

    To keep the fry from being sucked into the filter, use a sponge-type air-powered filter in the breeding tank. Hillstream loaches will spawn if the water temperature is raised to 77-78 degrees Fahrenheit for a short period of time before being returned to a chilly temperature.

    When the fry are ready to forage in the substrate, infusoria is an excellent meal, followed by micro worms and artemia nauplii.

    Are hillstream loaches and butterfly loaches the same?

    A variety of other names for the Chinese Hillstream Loach include the Butterfly Hillstream Loach, Hong Kong pleco, and Chinese sucker fish. These fish originate in Asia's swift-moving streams, and their streamlined bodies are designed to endure the powerful currents.
