well, i've got a 180g tank in my back yard that i've been thinking of bringing in for the last 3 years and i've never stocked it permanently but it's up and running now so i'm thinking of just keeping it outside. filtration is provided by a 15g sump with a QU2200 return(approx. 600gph) and if i can get it running again, a little giant on a closed loop(approx. 1200gph) for more current. for decorations i'm thinking a ton of anachris and driftwood and during the summer some hyacinth and duckweed. for stocking so far i'm thinking (3) comet goldfish, (15)white clouds, (3)pepper loaches, (12) zebra danios since the LFS has them 6/$2, (2) green sunfish (5) giant danios and possibly a couple madtoms would be cool. when the sunfish start trying to eat the minnow(if they do) then i'll rehome them.
