My own experience
I am new with planted tanks, but here is my experience:
Bought bronze crypto 6 weeks ago to put in a new small tank. Not having read anything about cryptos, I separated the rizhome into 5 smaller plants, and set them in the tank. Then I moved them arround almost every other day for the next 2 weeks until I got the look I wanted, while simultaneously setting up and tweaking DIY C02. If you ask the experts, that is a sure recipee for killing cryptos.
2 weeks ago the bronze was all droopy, and the oldest leaves where laying on top of the substrate, covered in detritus. I trimmed these leaves close to the crown, and having now read the experts, just expected the plants to die.
Last week most of my plants started pearling, and the oxygen bubbles uderneath the bronze's leaves makes them float and weave in the water. I have lots of new growth, and the largest plant put out 2 new leaves in 4 days.
SO MY non-expert advice would be: Move them, and if they seem to start melting, don't give up until they are definitely dead, they may resurrect sooner than you expect.
MY personal theory on why nothing happened to my plants, is that I have a Schroedinger's Planted Tank: Since I don't own any test kits at all, I have no way of observing my water quality parameters, and beign unobserved, they remain in an indeterminate state; the cryptos, not knowing if they are supposed to be dead or alive, just keep on growing. If things seem to be OK, I will never test my water parameters, and I advice everyone should do the same.
