: The Paroon Shark is listed as Critically Endangered on the IUCN Red List , with wild populations declining by over 99% due to overfishing and habitat loss.
: In the wild, they can grow up to 300 cm (nearly 10 feet) and weigh up to 300 kg. Even in captivity, they easily top 120 cm (48 inches).
: They are omnivorous and opportunistic. Adults will eat fish fillets, mussels, and large granules; in the wild, they have even been known to scavenge on carcasses.
: A juvenile might survive in a 300-gallon tank temporarily, but a fully grown adult requires several thousand gallons—essentially a massive indoor pond or public aquarium-scale system.
: They are relatively hardy but appreciate strong water flow and high oxygen levels to mimic their natural river habitats.
: Many experts argue that keeping these fish is unethical because they quickly outgrow almost all home tanks. Their skittish nature often leads them to swim into glass or decor, causing self-injury in cramped conditions. 2. Size and Space Requirements
