Duckweed in water feature?

[Cap10Squirty]

What do you all think about adding duckweed to the water feature of my GABF's enclosure? the plants are real small and I wouldn't think it would harm the frog if she ingested any, but of course I want to make sure before risking anything.

Duckweed can become a nuisance and be challenging to remove once it's reproducing well .

What plants do you recommend? And what would be a good plant for the frog to go through to remove clinging substrate?
