Most freshwater aquarium sharks are not true sharks but members of the Cyprinid family which also includes Barbs, Minnows, Danios and Rasboras. There are also a few catfish that have garnered the title of “shark” because of their physical appearance and feeding habits.
Some of these sharks (e.g., epaulette sharks, Hemiscyllium spp.) even exhibit specialized modes of locomotion that enable them to better move about within tight spaces. Many of these sharks also spend a considerable amount of time resting in reef crevices, especially during the day.
