Care at a glance
Species-specific aquarium care
- Tank: At least 24 in long and 12 in front to back for one adult (adults commonly reach about 6.3 in / 16 cm).
- Water: Freshwater.
- Layout: Lives on or near the bottom: floor space and hiding places matter more than height.
- Availability: Rarely or never seen in the aquarium trade; expect to source it from specialists or not at all.
Calculated from this species' own FishBase record: tank size from its typical adult length and swimming zone, water values from its recorded ranges. The group guide below fills in general care.
Care guide
Species care notes
- Tank: a base of at least 47 × 12 in (roughly 29 US gallons); space needed is rated “large tank”.
- Water: soft, acidic water, 72–79 °F, pH 6–7, 3–10 dGH.

- Difficulty: Moderate (Seriously Fish rating).
Short excerpts from the species profile:
- Setup: “A spacious tank is required, preferably with a sandy substrate.”
- Diet: “Not a very vegetarian Loricariid, it will accept most sinking dried foods, and also enjoys munching on meatier fare such as earthworms, prawns, mussels, bloodworm and suchlike.”
- Tankmates: “Generally peaceful with species inhabiting other parts of the tank.”
- Breeding: “It's probably not been bred in the hobby.”

Plecos (suckermouth catfish)
Applies to most species in this group. Habitat: South American rivers. Individual species can differ, so compare with the species numbers above and the linked sources.
Housing & setup
- Driftwood (some species rasp it for fiber), caves and good flow.
- Common plecos reach 18–24 in; many smaller species stay under 6 in.
Diet
- Algae wafers and vegetables for herbivores; meaty foods for carnivorous species.
Health watch
- Starvation if they're expected to live on algae alone.
