I believe the central american wood turtles require land and water areas. Judging by their adult size, you would not want to keep them in any small tank. Perhaps you can build an indoor pen that has a very large tank in it and a table around the top of it so that it has the land area it needs and the swimming area. Then you could also see it through the tank walls from below.
It is possible to cram many kinds of turltes into small tanks and see them survive, but if you want turtles to do well they need to have appropriate housing (for box turtles of north america, this means outdoors, it can mean different things for each species), but all turtles also need a good bit of room to exercise and move about. I am on a constant quest to expand my turtle pens and I'm moving mine from having about 12 square feet each to having at least 50 square feet each (per box turtle) and they keep using all the space I provide and doing better and better.
