Relevant Information:

Mature males of H. isbrueckeri have white to yellow seams to the distal margins of the caudal fin. Head covered with dermal ossifications dorsally, except for a naked area on snout tip, oval in shape. Dorsal margin of orbit not or very slightly elevated, continuing in a very inconspicuous ridge on posttemporal plate. Usually three scutes bordering posterior margin of supraoccipital; these scutes sometimes fragmented in four or five small scutelets. Body very low; dorsal profile gently descending from origin of dorsal fin to end of caudal peduncle. Caudal peduncle roughly ovate in cross-section; slightly flattened ventrally. Dorsal scutes between end of dorsal fin base and adipose fin spine flat in their dorsal portions; those closer to dorsal fin sometimes with a central area unprovided of odontodes. Aquarium Care: As with most of this genus, will do well in a larger aquarium, and the aquarium well filtered. Water parameters can be quite diverse for this genera. Diet: Omnivore with a liking for green, tablet and frozen foods. Remarks: The Hypostomus genus has 7 rays to the dorsal fin whereas the similar looking Pterygoplichthys species have 10 dorsal fin rays.
