Relevant Information:

Attractive looking as juveniles with large spots on a greenish/grey background. Similar to the Hypostomus genera but have longer bodies and have a shark type caudal fin shape (hence their genus name) with the lower fin lobe longer than the top. Aquarium Care: Non territorial and peaceful but they are messy eaters and as such good water quality would need to be adhered to. A large tank over 5ft (150cm) would be needed due to the eventual adult size of this catfish. Sexual differences: Adult males develop odontodes on their pectoral fins and also on the scutes of the posterior part of the body. Diet: Omnivore in the aquarium and is not fussy. Will also take vegetable foods.
