awesome creature!
are you talking about the blue spot stingray? it will require quite a large tank, the more surface area the better, so please take that into consideration.
it can be very tame and makes an awesome "pet".
if you are able to provide suitable housing...be sure the ray is active and alert, full bodied (not thinning out and not thin in the snout area between the eyes) and eating.

not something to purchase on a whim.
and i agree, has been known to up and die, just like that...maybe a cyanide issue????
