Crimson Loach - Schistura sp. Crimson : Complete Fish Profile & Care Guide
Table of contents
Introduction
The Crimson Loach (Schistura sp. Crimson) is a visually stunning species that has yet to be officially classified. This unique fish displays a peaceful demeanour towards other species of fish but not towards its own kind. When keeping Crimson Loaches, it is best to house them either singly, as a compatible pair, or in larger groups of 10 or more. Groups of only 3 or 4 can lead to unfortunate consequences, including the loss of specimens.
In general, Crimson Loaches do not show aggression towards other current-loving fish as long as they are not other nemacheilids. However, it is recommended to avoid small, placid tankmates and species with long fins. Small Barbs, temperate Bitterlings, Crossocheilus, Danios, Devarios, or Garras, are excellent companions for the Crimson Loach. When a shoal of these species is present, they will act as 'dither fish,' which will encourage the Loaches to come out into the open.
Crimson Loaches are highly territorial and require a spacious aquarium with highly oxygenated water and plenty of current. To establish a suitable environment for aquatic life, it is crucial to incorporate a sandy substrate in conjunction with a variety of interlocking and irregularly-shaped features, such as pebbles, rocks, pieces of slate, and tangles of driftwood.
This comprehensive arrangement promotes the necessary break-up of sightlines, creating a more natural and comfortable living space for aquatic organisms. Although plants are not found in great abundance in their natural habitat, robust species such as Anubias and Microsorum tied onto driftwood can help with water quality and create more hiding places, making the aquarium look more aesthetically pleasing. To ensure the Crimson Loaches thrive, it is essential to maintain excellent water conditions, including powerful filtration and regular partial water changes, as these fish will not tolerate a buildup of nitrates.
The Crimson Loach features an elongated, slim body that is a beautiful burgundy colour contrasted with dark stripes. All fins are translucent with a yellow hue, and the dorsal and caudal fins display intricate markings, making this species a striking addition to any aquarium.

Sexual Dimorphism
Distinguishing male and female Crimson Loaches is a relatively straightforward task. Fully developed males typically exhibit a more vibrant red pigmentation on the anterior region of their bodies, whereas their female counterparts tend to display a pinkish hue in this area and are often characterized by a fuller belly. Moreover, a majority of mature males present with enlarged cheeks when viewed from an overhead or frontal perspective.

Natural Habitat
Crimson Loaches are fascinating fish that originate from the southern regions of India, specifically Nilambur and Kerala. In their natural habitat, they can be found thriving in clear, fast-flowing forest streams with well-oxygenated water. These streams boast a unique composition of substrate consisting of sand, smooth gravel, and water-worn rocks and boulders.
While aquatic plants are typically absent in these habitats, there may be a small amount of marginal vegetation present, all while being surrounded by the lush canopy of a forest.
Breeding
As Crimson Loaches are currently an undescribed species, their breeding habits have not been documented or studied. Therefore, there is no conclusive information available on how to breed this particular fish in captivity.
Diet & Feeding
Crimson Loaches, being omnivorous in nature, demonstrate a notable preference for small live and frozen foods, including bloodworms, white mosquito larvae, vitamin-enriched brine shrimp, and daphnia. In addition to their preference for live and frozen fare, they also readily consume dried foods such as sinking catfish pellets, wafers, and granules. This versatile dietary inclination contributes to their adaptability and suitability for various feeding regimes in the aquarium setting.
