Description: 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. There are at the moment six L-numbers for this species and there is ongoing debate whether these are all separate species in their own right or the same but with different colour forms. Habitat: Very wide spread in the Amazon and Orinoco regions with different geographical colour variations. 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. Remarks: Still found on some online resources as Squaliforma emarginata.
