- Common name
- Albino bristlenose pleco
- Scientific name
- Ancistrus sp. 'common bristlenose' albino
- Category
- Freshwater fish
- Group
- Plecos and suckermouth catfish
- Environment
- Freshwater aquarium
- Origin
- Domestic aquarium strain; exact wild ancestry is unresolved and should not be presented as a confirmed Ancistrus species
- Care level
- Beginner to intermediate
- Adult size
- Commonly about 10–15 cm total length; exact maximum is line-dependent
- Expected lifespan
- Plan for roughly 8–12 years; some well-kept domestic bristlenose live longer, so housing must be permanent.
- Minimum housing
- At least 100 L with an 80 cm or longer footprint for one adult; 160 L or more for a compatible pair
- Temperature
- 23–27 °C
- pH
- 6.0–7.8
- Hardness / minerals
- 4–18 °dGH (approximately 71–321 mg/L as CaCO₃); exact wild-provenance range is unknown
- Salinity
- Freshwater; 0 ppt routine salinity
- Lighting
- Normal lighting with shaded caves and wood
- Placement / zone
- Bottom and hard surfaces
- Filtration
- Use mature biological filtration sized for the complete adult albino bristlenose pleco group, with guarded intakes and accessible mechanical capture. Keep flow moderate to strong with calm cave interiors where the fish lives, and maintain undetectable ammonia and nitrite.
- Aeration
- Maintain reliable surface agitation and oxygen exchange at all times. Increase aeration during warm weather, medication, transport recovery, heavy feeding or any sign of rapid breathing.
- Maintenance
- Perform regular matched-water changes guided by nitrate and waste, remove uneaten food and trapped detritus, clean mechanical media without disrupting the biofilter, and record feeding, body condition, respiration and aggression.
Identity and search names
Domestic albino common-bristlenose profile. Exact species ancestry is uncertain; Ancistrus cirrhosus may be used only as a comparison, not an automatic identification.
Search names: albino bristlenose catfish, albino bushynose pleco
Environment and housing
Mature aquarium with smooth caves, wood, shaded surfaces, high oxygen, strong filtration and guarded intakes
Social structure: One adult or a compatible pair; mature males defend caves and floor space
Feeding and nutrition
Feeding ecology: Biofilm, algae, plant material and complete algae-rich sinking foods, with vegetables and modest animal protein
Feeding routine: Feed daily and confirm food reaches the fish after lights dim; aquarium algae alone is insufficient
Breeding, reproduction or spread
Cave spawner
Detailed care and app-ready planning
- Identity scope
- Domestic albino common-bristlenose profile. Exact species ancestry is uncertain; Ancistrus cirrhosus may be used only as a comparison, not an automatic identification.
- Adult size and space
- Common domestic adults are roughly 10–15 cm total length. Use at least 100 L and an 80 cm footprint for one, with more space for a pair.
- Social structure
- One adult is simplest. A pair needs several caves and enough floor area; multiple mature males require much larger territory.
- Swimming zone or placement
- Bottom and attached surfaces, especially caves, wood, glass and rock.
- Feeding ecology
- Grazes biofilm and plant material but also consumes varied prepared food and occasional animal matter.
- Feeding plan
- Provide algae-rich sinking foods, vegetables and modest protein every day. Feed after lights dim if necessary and remove spoiled vegetables.
- Water stability
- Maintain 23–27 °C, pH 6.0–7.8 and roughly 4–18 °dGH. Exact ancestry is unknown, so avoid extreme water and abrupt changes.
- Habitat structure
- Use smooth caves, wood, shaded surfaces, high oxygen, strong biological filtration and protected intakes.
- Compatibility plan
- Avoid aggressive bottom fish and any arrangement where one fish controls every cave or all sinking food.
- Breeding or reproduction plan
- Provide a secure cave and separate fry plan. The male guards the clutch; monitor condition and avoid repeated breeding that exhausts adults.
- Quarantine
- Quarantine in a cycled aquarium and confirm feeding, faeces, abdomen, skin, fins and respiration before introduction.
- Welfare checks
- Check abdominal fullness, feeding, faeces, respiration, cave access, abrasions and aggression between males.
- Biosecurity and release
- Never release fish, eggs, fry, aquarium plants, water or sediment into drains, dams or waterways. Before import, sale or interstate movement, verify the exact identity in current BICON and the Live Import List, and check the South Australian noxious-fish rules.
- Main risk
- False species labelling and underfeeding an animal sold as an algae cleaner.
- Adult projected load
- Project biological load from the full adult albino bristlenose pleco group, adult body mass, feeding pattern, activity and social requirement rather than juvenile sale size. This domestic pleco has a high solids load for its length because it grazes and feeds continuously.
- Filtration
- Use mature biological filtration sized for the complete adult albino bristlenose pleco group, with guarded intakes and accessible mechanical capture. Keep flow moderate to strong with calm cave interiors where the fish lives, and maintain undetectable ammonia and nitrite.
- Aeration
- Maintain reliable surface agitation and oxygen exchange at all times. Increase aeration during warm weather, medication, transport recovery, heavy feeding or any sign of rapid breathing.
- Maintenance
- Perform regular matched-water changes guided by nitrate and waste, remove uneaten food and trapped detritus, clean mechanical media without disrupting the biofilter, and record feeding, body condition, respiration and aggression.
- Overridable warnings
- Non-overridable: do not accept persistent ammonia or nitrite, oxygen distress, starvation, chronic aggression or inadequate adult space. Different equipment, stocking or maintenance methods may be used only when measured water quality and adult welfare remain equivalent or better. Do not present the albino line as a verified wild species, and do not treat the fish as algae-cleaning equipment.
Compatibility, welfare and risk
Compatibility: Peaceful community fish that do not block caves or steal all sinking food; avoid multiple adult males in limited floor area
Welfare: It produces substantial waste and must be directly fed. A pleco is not algae-cleaning equipment.
Main warning: The albino common bristlenose is a domestic trade form, not proof of Ancistrus cirrhosus. Do not publish uncertain ancestry as a wild species.
Biosecurity and release
Never release fish, eggs, fry, aquarium plants, water or sediment into drains, dams or waterways. Before import, sale or interstate movement, verify the exact identity in current BICON and the Live Import List, and check the South Australian noxious-fish rules.
