• General Overview

  • The Hovering Loach is a small, fascinating freshwater loach often associated with hillstream or river-dwelling species.

  • Named for its unique behavior, this fish appears to “hover” or glide against surfaces using its flattened body and strong fins.

  • At 2.5–3 cm, these are juvenile specimens that adapt well to aquarium life when provided with clean, oxygen-rich water.

  • Ideal for aquarists who enjoy observing natural behavior rather than flashy coloration.

• Appearance & Body Structure

  • Flattened, streamlined body adapted for clinging to rocks, glass, and driftwood.

  • Broad pectoral and pelvic fins act like suction cups, allowing it to resist strong currents.

  • Natural coloration ranges from light brown to grey with subtle patterns or mottling for camouflage.

  • Eyes are positioned high on the head, giving excellent visibility while resting on surfaces.

  • Coloration becomes clearer and more contrasted in well-oxygenated, stress-free tanks.

• Natural Behavior & Activity

  • Peaceful, calm, and non-aggressive by nature.

  • Spends most of its time attached to hard surfaces such as stones, aquarium glass, and driftwood.

  • Actively grazes on biofilm and algae throughout the day.

  • Enjoys moderate to strong water flow, mimicking natural river conditions.

  • Best kept in small groups of 3–6 to encourage natural behavior and reduce shyness.

• Adult Size & Lifespan

  • Adult size: Approximately 5–6 cm

  • Juveniles grow steadily under proper care.

  • Average lifespan is 5–8 years in a well-maintained aquarium.

  • Growth rate is slow to moderate.

• Tank Size & Aquarium Setup

  • Minimum tank size: 60 liters (15–20 gallons), larger recommended for groups.

  • Best suited for river-style or hillstream aquariums.

  • Requires smooth rocks, pebbles, and driftwood for grazing and resting.

  • Fine gravel or sand substrate is recommended.

  • Strong filtration and good water circulation are essential.

  • Live plants such as Anubias, Java fern, and mosses are suitable and appreciated.

• Water Conditions (Freshwater Requirements)

  • Temperature: 20–24 °C

  • pH: 6.5–7.5

  • Water hardness: Soft to moderately hard

  • Ammonia & Nitrite: 0 ppm

  • Nitrate: Below 20 ppm

  • Requires high dissolved oxygen levels and clean water.

  • Weekly water changes of 20–30% are strongly recommended.

  • Sensitive to poor water quality and sudden parameter changes.

• Feeding Habit & Diet

  • Omnivorous grazer with a strong preference for biofilm and algae.

  • Diet should include:

    • Natural algae growth on rocks

    • Algae wafers

    • Sinking pellets

    • Blanched vegetables (zucchini, spinach, cucumber)

    • Occasional frozen foods like daphnia or bloodworms

  • Feed once or twice daily, ensuring food reaches the bottom.

  • Supplemental feeding is important in very clean tanks with low algae growth.

• Tank Mates & Compatibility

  • Compatible with peaceful freshwater fish, including:

    • Small tetras

    • Rasboras

    • White cloud minnows

    • Corydoras

    • Small danios

  • Avoid aggressive or large predatory fish.

  • Not suitable with fin-nippers or territorial bottom dwellers.

  • Best kept with species that enjoy similar cooler, well-oxygenated water.

• Care Level & Maintenance

  • Care level: Intermediate

  • Not recommended for newly set-up aquariums.

  • Requires stable water conditions and strong filtration.

  • Regular tank maintenance is essential for long-term health.

  • Gentle acclimation is required when introducing to a new tank.

• Health & Special Care Notes

  • Generally hardy once established.

  • Sensitive to medications containing copper.

  • Stress may show as inactivity or loss of appetite.

  • Ensure sufficient algae or supplemental food to prevent starvation.
