Am I mad to put this in a tank and try to grow it as a carpeting plant?

It's apparently an indoor plant, according to the BBC:
It just looks so right! But can tell am about to be punished. Not pearling, but has lasted four days with almost no yellowing so far.

It's apparently an indoor plant, according to the BBC:
Best known as an indoor plant, baby's tears, or mind your own business, makes an attractive and maintenance-free alternative to grass as ground cover in moist, shady areas. It will tolerate sun or shade. Frost hardy, its leaves are killed by winter frost, but it will recover to grow vigorously in spring. The masses of tiny leaves clothe slender spreading stems that root as they run, forming a dense deep-pile carpet. As it covers the ground it will run over rocks, fallen logs, and so on, clinging to their shape so the features of the landscape are picked out. Quick to establish, it survives periodic dry spells and recovers quickly afterwards. It is a superb substitute for moss in a Japanese garden or shady courtyard. Propagate by division from spring to mid-summer.
