Hi I am new to the forum! I'm not sure how to make my own question so I'm going to piggyback on yours! I'm currently in the process of creating a new terrarium for my froggy friends out of an old curio cabinet. I have everything sealed with aquarium silicone and mod podge to be sure no harsh chemicals get through, however I created my waterfall using a pretty small amount of duct tape..some of the tape is exposed, and the rest is firmly in place under the rocks and "pond and stone" "great stuff". Its not going to come off easily, so I'm really hoping I didn't screw up..basically all I need to know is, is the duct tape toxic to my whites tree frogs or will they be safe? I've got two 13 yr olds and two 6 yr olds.. I've had them more than half of my life and am not willing to put them in any danger..All answers appreciated!!! Thank you!!
