Hillstream Loach: A Quick Overview
Hillstream loaches are small, freshwater fish. They are known for their unique, flattened bodies and ability to cling to rocks and other surfaces using suction cups on their underside.
Hillstream Loach History
A native of fast moving rivers and streams of Asia, this fish with a streamlined body is able to withstand strong currents. The aquarist can replicate these conditions by installing powerheads.
The hillstream loach fishes are referred to as Cypriniformes and Cobitoidea, with the superfamily further split into eight subgroups.
Appearance of Hillstream Loach
At first glance, one might confuse the loach with the cat fish. However, they are totally different even though they share a few similarities. Some features of the hillstream loach fish are:
- Presence of barbels around the mouth, 3-6 pairs
- Having very few to no scales. Most of them have smooth bodies
- They are torpedo-shaped
- On the lower edges of their fins are minute spines that aid them with resisting the drag of fast flowing water
- Flattened undersides that almost make them resemble snakes. Those with highly flattened undersides are believed to have previously inhabited streams with faster running water as opposed to those with less flattened undersides
- Have slightly large fins used to wing themselves into rock crevices
- Have sucker type kind of mouth
- The length is about 2 to 3 inches
- Have low-affinity haemoglobin
- Have got modified pelvic and pectoral fins leading to a powerful suction-like cup which allows them to cling onto rocks, crawl and even eat on surfaces that are prone to high speed waters
Tank Requirements for Hillstream Loach
Remember the hillstream loach fish was specifically used to very fast-moving water and the body is adjusted to it. Tank conditions should at least meet certain percentage of its original home to make its life comfortable or at least bearable.
It should not be lost on an aquarist that the hillstream loach fish cannot survive in an ordinary standard tank. Sharing its home with other fishes which need relatively calm tank conditions may not therefore work. Some of the adjustments for their tank should include:
- External canisters to provide powerful filtration
- Additional power-heads for adequate flow of water. This also ensures there is a high supply of oxygen to help the fish thrive
- Power filters are another necessity as they impart the needed tumbling action that acts like fast speed water
- A river-tank manifold can be adopted for an effective water flow. The tubes should be non-perforated
- The tank has to be high and long. As a matter of fact, fast flowing water will easily push the fish at high speeds and a small tank will inconvenience its movement. The tank should not be smaller than 3 feet
- pH level range is supposed to be 6.5-7.5
- The best temperature is between 65 and 75 degrees Fahrenheit
- The best water type is kH 10-15
- Sand and fine gravel are the best options as the smooth body can be harmed by rough sand. Do not forget that they often swim at the bottom of the tank. Since they use high-speed waters, rough sand may be abrasive to them
- Some smooth rocks can be added too
- Bright light is necessary to offer the best environment for the growth of algae. The 40 watt tubes are a good option. If they are at least 4, the better
- Hillstream loaches are best in school of three or four. Placing them in the tank singly may not auger well with them as they are a territorial lot
- Provide them with sturdy plants and driftwood to give them sufficient hiding places
- Changing water weekly is ideal as they love swimming in clean water
