First of all I would like to say hello to the forum. I recently rescued two baby r.e.s. from the flea market. Unfortunately one passed away recently and the other one is out growing his 12 gallon fish tank so I've been thinking about putting a pond in the back yard. Here is a chart from wikipedia of the average climate of the city I live in: http://en.wikipedia.org/wiki/San_Antonio#Climate . Would it be okay to leave him in there year round? How big should the pond be? Lastly, I'm going to college in two years and I don't want my parents to have a big burden on there back so will a pond require a lot of maintenance?
