I finally decided what to do with my valintine's day present (265 gal tank) my wife got me. After much debating between fresh or saltwater I went with fresh. Currently houses three tiger oscars and three albino oscars, all about 2", and some snails. I decorated with a deep substate of sand, some large rocks, and lots of driftwood. Anyone have suggestions on live plants that would look nice and be easy to grow. Also can I add crabs or crayfish to my tank or is that asking for trouble?
