if you truly have this turtle return it to the ocean or find a resue group in your area to take it.
1) its illegal to harvest turtles they are an endagered species
2) the get way to big for anything other than what a aqurium can keep them in
3) at the risk of sounding harsh is that its irresponsible to harvest an animal that people are working so hard to keep from going into extinction and keep in an aquarium with out any consideration of what it will do to the animal and not knowing what they eat.
as I said please find a rescue group or return it to the ocean where you found it so atleast it has a chance of survival and you dont dont get thrown in jail.

again I dont want to sound harsh or anything like that but you really need to contact someone about this a rescue group or someone that can help this turtle have the best chance of survival. there are way to many people that are trying to keep this animal from going into extinction.
FWIW
