Identification: Need help Identifying two tropical plants

These plants I bought for my vivarium were bought at Rona, simply labeled "4 inch tropical plants" and nobody seemed to be able to help me identify them.

Hopefully some of you can help!

Thanks :)

Edit: I think the first is "Dracaena Warneckii"

 

The first one looks like Dracaena fragrans 'Lemon Lime' (syn. Dracaena deremensis 'Lemon Lime').

 

The second plant might be some kind of Croton.

 

Possibly, but I googled it & can't find anything similar. But then again, according to wikipedia there's about 3487394738 species of Crotons

Alright that's what i thought because I was browsing and saw something similar on another post.

Any idea if it's toxic to lizards? =\

 

It is toxic to animals according to this document. Caution is in order.

 

Well, that sucks.

I guess as a precaution maybe I should just purchase something else & replace it.
Thanks for your help :)

 

Something about the vein pattern and shape of leaf makes me think that second one is a croton. have no idea about the variety though. My croton looks similar to that one but the veins get yellow and red. Dont know the name of mine either.
