Ok so I already know most everything that I need to to keep and raise a leopard gecko properly but I had a question. I have a custom made 4x2x2 tank that I had originally used for my beardie (Ed) when I still had him and was wondering if I would be able to use this for a leopard gecko or if this size of tank would be just too overwhelming. I plan on using an empty 20g long for the start, just till I can get Ed's old tank cleaned out, but I was still curious on whether anybody else has used an over sized tank for a leopard gecko or not and what positive/negative effects it may have.
