The most important consideration when purchasing a shark/ray for the home aquarium is its potential size. Most aquarium varieties grow to well over 2 feet in length and require extremely large aquariums with vast swimming spaces to survive. Aquarium sharks/rays are bottom dwelling species of fish and often enjoy burying themselves in the ocean floor. For this reason it is important to house them in an aquarium with a soft substrate of sand or very fine gravel. Sharks/rays also require optimal water conditions to survive and careful attention should be paid to the filtration and water parameters of the aquarium.
Sharks/rays are carnivores and can be fed on a diet of fish, shrimp, squid and scallops.
