The title says it all, is duct tape safe for use in frog terrarium? It's a very small amount around the top of their waterfall. Some of it is covered by "great stuff - pond and stone" and rocks I used to make the fall, so it is very hard to remove, or I would just take it off to be safe.. So before I go through all that trouble, Is it toxic? They are Australian whites tree frogs. I have two 13 yr olds and two 6 yr olds )

Thank you for your help!
