Yeah... though I DO miss having koi and giant goldfish out in the back (and my albino catfish, Tuna! I miss her!
I raised her from a fry!).
We still have three giant goldfish that we kept for ourselves (they're about a foot long, each, just cruising in a temporary tank). I know my dad still wants to put the pond out back again (especially since he bought a duckling around Easter for my sister!). I've gone over a few designs with him about it...
But back to business. Paludarium (which is really hard to spell, haha). I think the southeast Asian theme would work best. What I might do is set up a sort of platform towards the back of the tank for land, or simply slope it down towards the water. Depends.
