An adult rainbow shark thrives in a minimum of 55 gallons of water, with an aquarium length of 48 inches, at the neutral pH range (6 to 8 pH), with temperatures between 24 and 27 °C (75 and 81 °F), and water hardness maintained at 5 to 11 dH. They must have this much space, as they frequently swim around quickly and will terrorize other fish ...
Full-sized adult epaulette sharks are most successfully housed in tanks at or exceeding 680 litres (180 US gal), while adult bamboo sharks require more space and are known to do well in 910-litre (240 US gal) aquaria. [9] Hemiscyliids in captivity are provided artificial caves in which to hide.

[16] It requires a tank at least 300 centimetres (118 in) long, with sufficiently deep hiding places. [11]
