I think this topic would be a good idea for people like myself who are brand spankin' new to this wonderful hobby of keeping dart frogs. I plan on using SCS 1200 silicone and Great Stuff for my background, but cannot for the life of me locate these two items locally. Does anyone know anywhere online (United States) that you can order these and get them shipped to you? Now a question I have about the GS is which exact one should I get? They have multiple different ones and don't want to make a mistake that could be detrimental to my future inhabitants health. Thank you to any and all who can help me.
