They bury them in sand/soil and leave them to their desitny
They lay them in a sand pit that they have dug, then covers it up with sand, sheltering the eggs until they hatch.
They hatch out of eggs.
I am not sure I quite understand your question. Why put tortoise eggs in a water tank? Go to the Tortoise Trust website for information. www.tortoisetrust.org
Tortoise do not sit on their eggs (they are not warm blooded so they can not warm them), they bury them in a nest made in a warm moist place and they hatch naturally.
Like a mythical dragon, tortoises tend to hatch when they think the occasion is right, especially when the planets align, a suitable caretaker is nearby, or on a blue moon. If the tortoise is retarded (like the majority of them), then it will probably hatch whenever it feels like coming out of it's little shell. Unfortunetly, the stupid human caretakers will think that the eggs are duds and will dispose of the eggs before they want to hatch.
depends on temperature its being incubated. It usually takes around 80 - 120 days.

Once the female tortoise lays and buries her eggs, she has nothing more to do with them. When the eggs hatch a few months later, the babies are on their own and never know their mother.
