L231 is an unidentified Hypostomus, a large suckermouth catfish said to be exported from the upper Amazon region of Peru. Precise details of its origin are lacking. It grows to 250 to 300 mm SL and needs an aquarium of at least 180 by 60 cm, and it is unclear whether it is the same species as the similarly nameless L266.

Etymology

Edit

Hypostomus: from the Greek ὑπό (hypó), meaning 'under, beneath', and στόμα (stóma), meaning 'mouth'.

Distribution

Edit

Supposedly exported from the upper Amazon region in Peru but precise details are lacking.
