During the daytime, you can often find them climbing on the glass in a side-to-side crawl or fluttering their fins on the ground while searching for food. The hillstream loach has a highly patterned and streamlined body that is built to grip tightly onto rocks and withstand rushing rapids.
Originally found in tropical regions of Vietnam, Laos, and Cambodia, hillstream loaches live in shallow riffles, river rapids, and slower-moving stream pools in between. Their native habitat tends to have lots of rocks and is sparser in vegetation. Because heavy rainfall can stir up sediment and cause fluctuating water parameters, they are quite hardy and can handle a wide range of environmental conditions. Most of the initial research into this species says that they are a cool water fish that must be kept in a river manifold tank with fast current and high oxygenation.
We have personally kept them in hot water tanks with clown loaches, unheated setups with goldfish, and even heavily planted gallon tanks with gentle sponge filters — and the hillstream loaches happily thrived and bred in each of those different settings. Make sure to use a tight-fitting aquarium hood or top because hillstream loaches can easily climb out of your aquarium.
In our opinion, what they really appreciate is a stable pH preferably from 7. Also, keep a tight lid on the aquarium since they have the ability to climb up glass walls and escape.
If your hillstream loach is missing, try looking in your filter because sometimes they like to crawl inside. This species will not bother any fish that looks physically diverse to them. Tiger Barb , Oscar fish and African Cichlids. Less dominant, similarly-shaped Loaches will be bullied to starvation, such as: Homaloptera; Annamia; Hypergastromyzon; Liniparhomaloptera; Gastromyzon; Vanmanenia; and Formosania.
Hillstream Loaches are one of the most peaceful species of fish, suitable for community tanks and are not exclusively aggressive. Males can display dominant and territorial behaviour when it come to guarding their own personal spots. Hillstream Loach males engaged in fights will often push against each other belly-to-belly in a show of dominance, though this is intended as more of a display rather than intent to harm the other.
Hillstream Loaches are very social and it is advantageous that they are kept in groups of at least 6, though the more loaches per tank the better. A Hillstream Loach on its own will become lonely and anxious. Goldfish are a friendly species that will co-exist happily with Hillstream Loach.
Both have similar water parameters and fish keepers will need to provide a large enough space with plenty of food, hiding spot, and well-oxygenated water for them to thrive. Goldfish will need an area where the water flow is a little less intense so that they can rest. Dwarf freshwater shrimp such as Neocaridina davidi make excellent tank mates for Hillstream Loaches as they are a peaceful species and hail from the same continent, making their water parameters compatible.
Because Hillstream Loaches need fast water flow in their tank, the shrimp will need places where they can get out of the strong current, such as caves, clay pots, and rocks. Therefore these two species are incompatible, as they have diverse tank set up demands. In the wild Angelfish live in deep, slow-moving rivers and lakes, thus depositing them in a tank with a fast-moving current will stress this fish out, hindering their feeding and breeding.
Angelfish are also very territorial and will bite the Loaches, who will perish quickly from the stress. Thus, Hillstream Loaches and Angelfish are incompatible tank mates and should not be housed together. Axolotls also find fast water currents very stressful, therefore they are not compatible with Hillstream Loaches. Discus inhabit slow-moving waters and are not comfortable in fast currents, hence they are not compatible with Hillstream Loaches.
The Otocinclus appreciates moderate to slow-flowing streams and compact rivers, making it an unideal tank mate for Hillstream Loaches, who need fast-flowing water in their tank. Bettas have difficulty swimming in intense water current and if the filter is too powerful it can even suck the Betta into the intake tube, drowning the fish.
Bettas are also incredibly aggressive and will fight each other to death, with even their females getting into violent skirmishes. Thus, Hillstream Loaches and Betta are not compatible tank mates. Corydoras generally live in South American, slow-moving, marshes, streams, rivers, and ponds. Despite this, the Corydoras adore fast-flowing water and are often found playing and mating in them. Hillstream Loach and Corydoras are compatible, provided that fish keepers supply their tank with plenty of shelves and plants to rest from the strong currents.
While Hillstream Loaches are difficult to breed, it is not impossible to do in captivity if the correct environment is supplied. This species remains the easiest to breed out of the Loach species. Hillstream Loaches are sexually dimorphic and fish keepers can tell them apart when they reach adulthood, as juveniles are incredibly hard to sex.
Therefore, if fish keepers are intending to breed their Hillstream Loaches, they might need to buy a large group of juveniles. Minimum Tank Size. Temperature Range. Water Hardness. Needs pristine, well-oxygenated water and a strong flow rateaptivity.
Water type. Egg layer, extremely difficult to breed in home tanks. Peaceful with other non-aggressive community fish. OK, for Planted Tanks? Reticulated loaches are members of a large family of different Hillstream loach varieties that are found in decreasing numbers in southeast Asia, China, and parts of India.
These fish are found in fast-flowing streams, spending much of their time foraging on the stream bottom or clinging to rocks. Reticulated loaches are not strictly regarded as schooling fish, although they are often seen living in small groups.
The striping on the dorsal and caudal fins tends to be more linear than that of the body. A sucker mouth and flattened underbelly are also perfect for grazing on algae and withstanding the force of the water.
Reticulated Hillstream loaches are small fish, measuring around 2 to 3 inches in length. Their small size makes them ideally suited for foraging for food in tiny crevices and cracks in the rocky landscape of the riverbed home. Tank-kept Reticulated Hillstream loaches generally live for 8 to 10 years, provided that they receive a high-quality diet and the water in their tank is kept pristine and well-oxygenated.
Reticulated Hillstream loaches are peaceful creatures that make a lovely addition to a community of small, non-aggressive species that share similar water requirements. These fish are quite active foragers, spending much of their time grazing on algae, stuck to the tank glass, or rooting around among the base of plants and in rocky crevices. Wild Reticulated Hillstream loaches are not natural schooling fish.
However, when kept in a home aquarium, it seems that these little guys do prefer the company of their own kind. For that reason, I recommend that you keep a group of at least three loaches. That said, if the bottom of the tank becomes overcrowded, territorial scuffles can break out. Generally, invertebrates such as shrimp and snails are safe to keep with Reticulated Hillstream loaches.
Fish that are best avoided are large, territorial species such as cichlids and Oscars, and Angelfish and Tiger barbs that can be nippy and might harass and stress the loaches. All Hillstream loaches are omnivores, grazing on biofilm and algae on the tank surfaces. Fish flakes, mini pellets, and algae wafers can also be added to the diet. Yes, in theory, your loaches will enjoy the inclusion of some live food in their diet every now and then.
They're pretty neat to look at, but probably more ambitious than what you're looking for. Adding an airstone would be much easier and likely suffice. As for hillstream loaches which I am just going to lump them all in together despite being incredibly diverse, high oxygen low temp environments with a planted or hardscaped environment makes them feel secure.
If you really want to entertain them you can add a small power head or fan to the tank, they enjoy currents. I'm a noob but I have 5 Hillstream loaches. I have a HoB and also a sponge filter. I keep the tank between degree F. I have sand substrate with lots of rocks and plants. I have 3 fans, 1 small one that runs almost continuously. I just purchased a lot more rocks that I will be setting outside in the sun in water so they grow algae.
I will then be doing a continuous rock swap with the ones in the tank so they have a nice supply of algae to graze on. That's what I plan to do! Hillstream loaches with gobies probably some stiphodon or other? With a small school of white clouds.
