AHAA, YES, tanks for SHARKS, hers what my daughter does
1. egg
[hr]
> in a 55gal for one year by then the shark should be 18" an going threw it's NIGHT MANEUVERS, an making LOTS OF noise in the tank.
2. then 125gal. for more SWIMMING ROOM, growing to 26"
3. an NOW she should need a tank at leaast 3 times her lenth, so she can SWIM, an at least 1 1/2 times he lenth wide, so she doesn't get cramped when turning around, I would look into a 8x3x2 size tank if you plan on keeping that fish for a LOOOONG TIME, heres a pic of a another species of shark so you can look at SIZE it should get. this one is 38" long her body is about 8" wide. an her fins are 5" each Putting her Total WIDTH at about 18" from FIN TIP to FIN TIP, Id say she will need some turnning ROOM, when reaching adult size.
GOOD LUCK GOOD REEFIN"
