Hello everyone. So this has been a long time coming and I am beyond excited. I have always wanted to build a vivarium for dart frogs and my opportunity is finally here. I have now bought all my supplies and so now I am at that point of nervousness to actually begin. My tank is 30" L, 12" w and 18" tall. I will be building the background out of foam and right now that is the biggest thing that is making me nervous.. I would love some impute on the best way to go about doing this part. Is it hard to control? Does it stay where you want it to go? (I am using gaps and cracks by the way) Will it at all stick to the glass or will it be easy to remove to put the substrate all over it?

Well I will start with that for now. I am sure I will have lots more questions along the way however..

Thanks for everyone's help,
Rachelle
