The FRT and Mata Mata are your only choices for a fully aquatic turtle.
Softshells are great swimmers, but they are not fully aquatic. As far as I'm aware, ALL softshell species need access to a basking area.
Turtles are not adapted to live like fish. They use dry basking areas to keep healthy, preventing fungus and bacterial growth on their shells, and clearing respiratory infections. Some species, like Softshells and Musks, are often said to "rarely bask". This ISN'T the case, they are just very nervous baskers, and are unlikely to bask when you are watching. They will bask when you are not around, and dive into the water at the slightest disturbance.
If that's not enough to convince you, Softshells are hugely carnivorous, and fish make up a large portion of their diet. I've had Softshells take down fish twice their size.
Best,
Paul
