[Ebook] 500 freshwater aquarium fish – Catfish – Painted Talking Catfish (Acanthodoras cataphractus)
Of the three species in the genus, two—Painted Talking Catfish and Talking Catfish (A spinosissimus) from Ecuador or eastern Peru—are frequently encountered, in the hobby, while the third, A calderonensis, is only rarely available. Both talking catfish species are often confused. However, the “granules” on the skull are much sharper in A spinosissimus; and the gill cover in Painted Talking Catfish has fine grooves, while in A spinosissimus it is granular in texture.
