It's believed that the first Red Whiptails were bred in the former DDR in the 70's, and that the first ones were imported from Paraguay. This has not been confirmed, and todays aquarium strain could be either a morph of Leliella heteroptera or a cross between this and Hemiloricaria lanceolata. Certainly, crossbreeds are on the market, these grow bigger and get darker as they age. Also, the genus name Leliella (Isbrücker, 2001) is not accepted by all so the most commonly used name for this fish is still “Rineloricaria sp. Red”. Even it's l-number is controversial, as L10 was given to a different species of whiptail, and later L10a was given to L.sp.”Red”! As an aquarium fish, this is a calm, very peaceful species that doesn't compete too well with big, aggressive species. It should be fed a varied diet, and given clean, well filtered water. Males develop odontodes on their cheeks and their pectoral fins, and eggs are laid in tight tubes where the male guards them.
