I have been searching around lately for a new home for my Dumerils. He has outgrown his 20 gallon tank, and I don't want to keep using aquaria for his enclosure as they are expensive and heavy and awkward to deal with come cleaing time. I was looking at melamine to make the enclosure, I have the plan in my head, and am ready to build, I do have one question though that I hope someone can answer. Once completed, I had planned on using silicone to seal the joints (inside) to avoid the moisture build up and eventual wood destruction. I know aquaria use silicone to seal. Ok, after all that long winded babble, should I allow the silicone to set and then let the enclosure "air" out for a while? And are silicone fumes toxic to the animal? Is there another option beside silicone I can use to seal up the cracks and crevices?
Thanks a ton for any info you can provide....

P.S. How would a new BCC look in that 20 gallon once it is vacated by the current occupant?
