You can pluck pieces off a new plastic plant and let float, usually the plastic plants are linked with a connector and can gently twist off and be put back later.
The floating live stem plants usually do great floating at the top because they get good light being so close to it there.
Should be getting close to birthing.
Do you have food for the babies?
Hikari First Bites is a good basic food. You can buy live food cultures too. Vinegar eels, white worms. Grow Brine Shrimp and feed babies baby Brine shrimp.
