Looking to add color to my terrarium. Are these plants safe?

[Carisab]

Hello,

I found two plants that I really like and I don't know if they are safe. This is for a P. Terribilis dart frog.

One is Vinca Illumination, a creeping myrtle with bold yellow leaves. I know they are not safe to ingest, but are they PDF safe? I see pics of vivarium and I see myrtle in them. Does anyone have experience with creeping myrtle? I know it will take a lot of trimming.

The second is Persian Shield - Strobilanthes Dyerianus. I know it will take pruning to keep it small, but I love the beautiful purple leaves. It says it grows in humid warm climates. The plant I got is quite small.

Thanks for any help.
