Adding frogs & fish to our new pond in So Cal
So we just finished building our pond today in our backyard. It is about 10-11 ft long, 5 ft wide, and maybe 2 1/2 to 3 feet deep. I would like to add some plants like lilies and really would like to add some small koi and frogs. Is this size approiate for koi? I know this is Southern California and we don't have frogs really around, but I would like to add frogs to see and hear them, what kind would be good to have? Can I just go to petsmart and pick some out? Will the frogs escape even though my yard is really large and surrounded by a brick wall? I had thought about adding a water turtle since the kids are dying to have one, but it sounds like they dirty the water pretty bad and will escape, what do you think? Also I did add a 330gph pump and am buying the filter tomorrow, is this good you think?
Thanks for all the advice!
