They've laid their eggs yet again on the arch in their tank. They've been investigating the plants as well. Once the eggs hatch, they will need a clean place to attach their babies (fry) by their little heads, where they'll dangle until they grow stronger.
If they can get their eggs to hatch, perhaps the leaves will be used for the fry. Then as they grow larger and begin to swim, the plants will serve as a nice hiding place for them.
