Green Laser Loach - Gastromyzon lepidogaster
Green Laser Loach (Gastromyzon lepidogaster)
The Green Laser Loach is a rare and eye-catching hillstream loach from northern Borneo, prized for its flattened sucker-like body, smooth clinging fins and beautiful green to blue-green sheen over a darker patterned base. Also known as the Green Borneo Sucker or Green Laser Borneo Sucker Loach, this specialist freshwater loach is adapted for life in fast-flowing, highly oxygenated streams. In the aquarium it is a fascinating grazer that spends much of its time attached to rocks, glass and décor while feeding across mature surfaces.
Common Name:
Green Laser Loach. Also commonly referred to as the Green Laser Borneo Sucker Loach, Green Borneo Sucker, Green Hillstream Loach or Borneo Sucker Loach.
Scientific Name (Latin):
Gastromyzon lepidogaster
Maximum Size:
Up to around 10 cm in scientific records, although many aquarium specimens are usually seen around 5–8 cm.
Water Type:
Freshwater
Origin / Natural Habitat:
Native to northern Borneo, with records including the Temburong River drainage. Like other Borneo sucker loaches, it is associated with shallow, fast-flowing, highly oxygenated streams and riffle zones where it can cling to smooth rocks and graze on biofilm, algae and tiny microorganisms.
Water Parameters:
Temperature: 18–24°C
pH Range: 6.0–7.5
Hardness: soft to moderately hard water
Temperament:
Peaceful and non-aggressive. It is best kept with other calm, current-loving fish that will not outcompete it or disturb it constantly. It should not be mixed with large aggressive fish, warm-water species or boisterous bottom-dwellers.
Diet:
Omnivorous grazer. It should be offered a varied diet including algae wafers, spirulina-based foods, fine sinking foods, catfish pellets and small frozen foods such as daphnia, cyclops, brineshrimp and mosquito larvae. It also benefits greatly from natural algae, biofilm and aufwuchs growth within a mature aquarium.
Minimum Tank Size:
A practical recommendation is at least 80–100 litres for a small group, with a longer aquarium preferred so strong directional flow and open grazing areas can be provided.
Behaviour & Activity:
This is a specialist bottom and surface-grazing loach that spends much of its time attached to smooth rocks, glass, wood and décor. It is best kept in a group where possible and will often choose high-flow areas with strong oxygenation. In the right setup, it can be active and visible during the day, moving between rocks and grazing surfaces.
Aquarium Category:
Community Fish / Specialist
This species is peaceful enough for a community aquarium, but it is classed as specialist because of its environmental needs rather than aggression. Best kept with small, peaceful, cooler-water species such as White Cloud Mountain Minnows, peaceful danios, small gobies and other suitable hillstream loaches. Avoid goldfish aquariums, tropical tanks kept too warm, low-flow setups and species that prefer still water.
Special Requirements or Care Notes:
This fish needs a mature river-style aquarium with strong flow, excellent aeration, high dissolved oxygen and very clean water. Smooth rocks, cobbles, bright lighting for algae growth and open grazing surfaces are strongly recommended. It should not be added to new, sterile or poorly oxygenated aquariums. Extra powerheads, venturi flow or air stones can be useful, especially during warmer weather when oxygen levels drop.
Suitable for:
Intermediate fishkeepers
Availability:
Rare / occasional in trade
