AquaNexus verified profile
Whiptail catfish
Rineloricaria lanceolata
Identity-held profile for Rineloricaria lanceolata, a broadly distributed South American whiptail whose generic trade name often conceals other species or domestic lines.
Outcome: HELD Permanent ID: 731
Profile overview
- Scientific Name
- Rineloricaria lanceolata
- Identity and search names
- Rineloricaria lanceolata, Lanceolate whiptail
- Category
- Freshwater fish
- Subgroup
- Other catfish
- Environment
- Freshwater aquarium
- Origin
- Paraguay basin and additional Guaporé, Ji-Paraná, Purus, Solimões, Araguaia, Marañón and Madre de Dios drainages in South America
- Care
- Intermediate
- Adult Size
- Usually about 10–14 cm
- Lifespan
- 5–15 years
- Tank
- At least 150 L for a verified pair or small group
- Temp
- 23–28 °C
- pH
- 6.0–7.8
- Hardness
- Soft to moderately hard
- Salinity
- Freshwater; no routine salt addition
- Lighting
- Normal aquarium lighting
- Placement
- Bottom to mid water
- Diet
- Biofilm grazer and small-invertebrate feeder requiring plant-rich sinking foods, aufwuchs surfaces and supplemental protein
- Filtration
- Use mature biological filtration with effective mechanical solids capture and turnover matched to the species’ natural flow needs. Protect intakes, preserve established media during cleaning and keep ammonia and nitrite at zero.
- Aeration
- Maintain continuous surface agitation and dependable dissolved oxygen across the whole aquarium. Increase oxygen reserve in warm water, strong-current systems, dense groups, medication periods and power interruptions.
- Maintenance
- Observe feeding, respiration, body condition and social behaviour daily; test nitrogen waste and key chemistry on a schedule; clean mechanical media before trapped waste decomposes; and perform regular temperature- and chemistry-matched water changes.
- Welfare
- Maintain the stated adult space and social structure, verify feeding, and intervene early when injury, exclusion, weight loss, abnormal respiration or altered behaviour appears. “Whiptail catfish” is a broad trade label covering multiple Rineloricaria and domestic colour lines. Keep this profile identity-held and apply it only to verified R. lanceolata.
- Biosecurity
- Never release fish, fry, eggs, aquarium water, sediment, plants or live foods into drains, dams or natural waterways. Confirm current Australian import conditions and South Australian possession, trade and movement rules before acquisition or transfer.
- Review Status
- HELD
- Source Status
- HELD — identity, legal availability, acquisition suitability or evidence remains unresolved; the profile is complete but is not approved for acquisition. CURRENT
App-ready care, welfare and biosecurity details
Identity Scope
Single-species profile for Rineloricaria lanceolata. Preserve permanent AquaNexus ID 731, slug whiptail-catfish and route /species/whiptail-catfish/; retain former combinations, locality labels and trade names only as searchable aliases. The public trade identity is ambiguous, so apply this profile only after independent confirmation of the scientific species.
Adult Size And Space
Expected adult size: Usually about 10–14 cm. Minimum permanent housing: At least 150 L for a verified pair or small group. Plan around adult dimensions, activity, social structure, aggression, oxygen demand and waste production rather than sale size.
Social Structure
Peaceful pair or small group with multiple tubes, wood surfaces and feeding stations; ensure timid fish are not starved by robust plecos
Swimming Zone
Primary zone: Bottom to mid water. Keep that zone usable for movement, feeding, refuge and escape.
Feeding Ecology
Biofilm grazer and small-invertebrate feeder requiring plant-rich sinking foods, aufwuchs surfaces and supplemental protein
Feeding Plan
Offer small sinking meals once or twice daily and confirm abdominal condition; natural algae alone is insufficient
Water Stability
Maintain 23–28 °C; pH 6.0–7.8; hardness or minerals: Soft to moderately hard; salinity: Freshwater; no routine salt addition. Stable oxygenation and nitrogen-cycle control matter more than chasing one exact value.
Habitat Structure
Mature, well-oxygenated aquarium with sand, wood, leaf litter, smooth tubes and strong biofilm growth
Compatibility Plan
Do not combine small fish with catfish large enough to swallow them.
Breeding Plan
Tube or cavity spawner; the male guards and fans the adhesive clutch Parental care: Male guards and ventilates eggs until hatching.
Quarantine
Quarantine new livestock in a separate cycled system for at least 30 days. Observe appetite, respiration, waste, skin, fins and behaviour; use dedicated equipment and never add transport water to the established aquarium.
Welfare Checks
Maintain the stated adult space and social structure, verify feeding, and intervene early when injury, exclusion, weight loss, abnormal respiration or altered behaviour appears. “Whiptail catfish” is a broad trade label covering multiple Rineloricaria and domestic colour lines. Keep this profile identity-held and apply it only to verified R. lanceolata.
Biosecurity And Release
Never release fish, fry, eggs, aquarium water, sediment, plants or live foods into drains, dams or natural waterways. Confirm current Australian import conditions and South Australian possession, trade and movement rules before acquisition or transfer.
Main Risk
“Whiptail catfish” is a broad trade label covering multiple Rineloricaria and domestic colour lines. Keep this profile identity-held and apply it only to verified R. lanceolata.
Adult Projected Load
Plan filtration and stocking for the full adult size (Usually about 10–14 cm), the complete social group and peak feeding waste, not the current shop size. Permanent housing remains At least 150 L for a verified pair or small group.
Filtration
Use mature biological filtration with effective mechanical solids capture and turnover matched to the species’ natural flow needs. Protect intakes, preserve established media during cleaning and keep ammonia and nitrite at zero.
Aeration
Maintain continuous surface agitation and dependable dissolved oxygen across the whole aquarium. Increase oxygen reserve in warm water, strong-current systems, dense groups, medication periods and power interruptions.
Maintenance
Observe feeding, respiration, body condition and social behaviour daily; test nitrogen waste and key chemistry on a schedule; clean mechanical media before trapped waste decomposes; and perform regular temperature- and chemistry-matched water changes.
Overridable Warnings
The HELD trade-identity outcome cannot be overridden by the generic name whiptail catfish. Confirm the specimen against a defensible Rineloricaria identity, provenance, adult size and lawful acquisition pathway before approval.
