I've noticed this behavior in both E. tricolor and D. auratus. While in this position, the female will lay the eggs and then the male will usually fertilize the eggs. Don't disturb the eggs for a day or two, just to make sure that the eggs would be fertilized. The clutch should be taken out especially if the terrarium is set up for a colony. Other females in the group are known to strike the eggs with their tongues, damaging the eggs.
Females can be aggressive towards one another.
They would often be seen wrestling one another to win the right to mate with the male. If on the other hand you have a pair, the eggs can be left so that the male can attend to it. Make sure that there is a water source, such as a water bowl, so that the male frog can deposit the tadpoles in it. For species such as D. pumilio, D. histrionicus, and D. lehmanni, the eggs must be left alone for the parents to tend. The tadpoles of these frogs are exclusively fed unfertilized eggs by the females and would take nothing else.
