[Ebook] The New Guide to Aquarium Fish – Catfishes – Loricariids: The Suckermouthed Catfishes
The loricariids, from South America, are a most disparate family of catfishes, in both shape and size. All exhibit an underslung sucker mouth and most are herbivorous. The mouth is used to attach themselves to solid objects to avoid being carried away in the current, as they are particularly poor swimmers. The body is encased in body plates that develop from skin folds in the early fry stage, which in later life make swimming a difficult and laborious chore.
