Personally I would say the following minimums guidelines for "aquarium sharks". Note tank width should be greater than shark's maximum length.
For a shark between 24-28", at least 225-270 gallons (tank is at least 30" wide). For sharks between 29-32" at least 315-360 gallons (tank width at least 36" wide). For Sharks between 34-37" at least 420 gallons (tank width - at least 42" wide), For sharks that are between 38-42" - at least 480-540 gallons (tank width at least 48").
While it's possible to keep shark pups - up to about 1 year of age in a 90 gallon tank (basically 48"L x 24"W x 18"T). This is only for the 1st year - not for life. |
