Lovely frog! Have heard people say dont release because wherever she came from, the other frogs and she may have different internal parasite loads and different other things going on ( eg chytrid) so introducing a strange frog who has been in captivity may be bad for the frog you are releasing as well as the frogs who live where she us being released. Was the plant from outside near you? I used to have pacifics on a ranch who came in through windows and would just come and go. I took them with me when i moved because they sort of lived in my kitchen, and garter snakes were coming in after them. Now that they had been in captivity, i couldnt release them to a wild population of pacifics in another town ( different population of them). Just my two cents, dont know what others think.
