Building a plywood tank... Any thoughts

[hdrob]

I now have room for a plywood tank and hoping for some monster keepers to chime in with their thoughts. I was planning to end up around 600-800 gallons. Probably 8 feet long. My first thought was Charles' dorado. Any suggestions or tips for stocking? I already have cudas and vampires in a 180 with a tig. I'm looking for something a little bigger. :-)

Hoping to start building in a couple of weeks! Can't wait.

Gars rays aros snake heads. But for a pond i recommend rays cuz u can see them the best I'n ponds vs see only the top of a fish.
