Sucking Loach - Gyrinocheilus aymonieri : Complete Fish Profile & Care Guide
Table of contents
Introduction
The Sucking Loach (Gyrinocheilus aymonieri) is an intriguing and versatile species that can be a wonderful addition to any aquarium, but it requires special care and attention. Frequently observed is the trade of this particular species for its utility in consuming algae within the context of community aquariums. Regrettably, this behaviour predominantly manifests in juvenile specimens, as adults tend to demonstrate a diminished inclination towards algae consumption, instead displaying a heightened propensity for instigating disturbances among the tank's cohabitant organisms.
Aquarium companions should exhibit resilience and proficient swimming capabilities. Adult specimens often display marked territorial tendencies when cohabitating, especially with fish of comparable appearance. It is imperative to allocate sufficient space and incorporate suitable concealment opportunities. To mitigate inter-species aggression, consider maintaining them individually or within a substantial collective. Maintaining low numbers, such as 2 or 3 specimens, may lead to incessant harassment of specific individuals.
Sucking loaches can become aggressive towards other fish if they are not fed properly or if they do not have enough space and hiding places. When considering the upkeep of Sucking Loaches, it is imperative to ensure the provision of an ample aquarium space, given the species' eventual attainment of substantial adult size. A swift water flow rate and smooth rockwork or stones are highly valued within the aquarium setting. The inclusion of plant cover is advisable; however, it is recommended to select more robust plant species, as these fish have a tendency to damage delicate and softer-leaved vegetation.
Sucking Loaches are available in three different colours, including natural brown tones, golden orange with red eyes, and a golden-brown part-albino variation. Their unique appearance adds a touch of vibrancy to any aquarium. Overall, if provided with adequate care, feeding, and suitable tank mates, the sucking loach can be a wonderful addition to your aquarium.

Sexual Dimorphism
Accurately determining the sex of juvenile Sucking Loaches poses a challenge. However, mature females tend to have thicker bodies than males. During spawning, males develop tubercles on their noses, which is a noticeable feature that can help differentiate them from females.

Natural Habitat
The Sucking Loach originates from the breathtaking mountain streams and medium to large rivers of Southeast Asia. In their natural habitat, these fish thrive in fast-flowing freshwater and can be found darting around substrates of pebbles, boulders, sand, and gravel, often taking shelter in the company of submerged tree roots or driftwood.
The shallow, clear water of these streams allows for ample sunlight to penetrate the surface, creating a rich biofilm upon which these fish graze. Interestingly, the Sucking Loach is known to undergo seasonal migrations, during which it ventures into deeper waters. However, these fish are well adapted to their environment, and their unique characteristics and behaviours have captivated the hearts of aquarium enthusiasts worldwide.
Breeding
Regrettably, there is limited information available on the breeding habits of the Sucking Loach. It has been reported that adult fish may develop tubercles on their nose, indicating their readiness to spawn. However, successful breeding of this species in the aquarium hobby remains uncommon, with only a small number of individuals reportedly achieving success, primarily through the use of hormone treatments in farming settings.
Diet & Feeding
The dietary preferences of Sucking Loaches primarily revolve around their propensity for consuming algae. This species demonstrates a notable affinity for various forms of algae present within their aquatic environment. While they may readily consume algae, particularly during their juvenile stages, it's important to note that as they mature, their dietary preferences can evolve.
In some cases, adult Sucking Loaches might exhibit a shift in behaviour, displaying reduced interest in algae consumption and potentially inclining toward accepting other types of sustenance, such as prepared commercial fish foods or supplemental protein-based offerings. Thus, a well-balanced diet catering to both their herbivorous tendencies and potential omnivorous inclinations is recommended for their optimal health and nutrition.
