Is my Silver Fittonia / Nerve Plant dying?

Hello everyone, I’m concerned that my Silver Fittonia (Nerve Plant) might be dying. Recently, I’ve noticed yellowing leaves and or drooping. I’m growing it in 12-inch pot. I water it twice a week. Does anyone know what could be wrong or how I can save it? Any advice would be appreciated!

 

It looks like overwatering to me. Is there a drainage hole in the bottom of the pot? If not, repot it into a pot with drainage at the bottom.
Whether or not there is drainage, before you water it again, take it out of the pot and see if there are mushy roots and if the soil is still wet. You can cut away mushy roots. Put it back in the pot, and feel how heavy the plant is. Wait to water it again until the good-looking leaves begin to wilt. Feel how heavy it is then. From now on, only water it when it is almost that light. After you water it, be sure to empty the dish under it so that it is not sitting n water.

 

Thanks a lot

 

As insurance, I would root a few cuttings just in case the parent plant dies.

 

Thanks
