Generally speaking, yes.
HOWEVER, terrariums were not necessarily built to hold water so you run the risk of a catastrophic leak or even losing the entire contents.
My advice would be to NOT use a terrarium as an aquarium. But many have and have had no problems.
If you are tempted to try, check the terrariums seams where the pieces of glass come together. If they are sealed tight with silicone (like an aquarium) at ALL joints, this is a good sign. Fill it slowly with water, checking for leaks all the while. If you see a leak, then abandon the project.
Just remember, you fill a terrarium with water at your own risk.
