Submerged spider plant question.

Have had three large green spider plant babies in the freshwater aquarium
for 3.5 weeks and they are very green and growing.

Does anyone know how much longer they will last completely submerged like
they are?

There is also a common vine cutting with heart shaped leaves that seems to
be doing well after 2.5 weeks.

The spiders look beautiful with two foot long leaves.

Only time will tell I guess.
