I don't think it's T. fluminensis, but any of the suggestions here are possible, with only this pic to go on. Kiss, if you're unable to decide from comparing what you remember your plant looking like to pics of the suggested names given here, hopefully we'll get another pic when it (or a cutting of it) can get back to the conditions that make it happy & recognizable. Unless you happen to have a pic of it when it was still looking good?
Donald, if by Bolivian Jew, you mean Callisia repens, its' flowers are so small, they are virtually invisible. In some older sources with drawings, the blooms are shown correctly, but if one does an image search, the bloom pics are all C. cordifolia, not C. repens. Even reputable sources like MOBOT and several .edu sites show pics of C. cordifolia labeled C. repens. Not surprising since they are so similar.
Inch Plant (Callisia repens)
Callisia cordifolia is wildly different looking when it blooms. I've put pics of that in the DB here.
Inch Plant (Callisia cordifolia)
After having both for several years, the differences are striking, numerous, and when one of them is in bloom, very obvious. Most notably, C. repens is purple in the back, doesn't bloom (visibly to humans.) C. cordifolia leaves are green on the back & the blooms are quite noticeable. I've tried to document the differences with the pics I've added here. What do you think?
