I would suggest still having an inch or 2 of Terra-lite or Hydroton for a drainage layer. Place some screen over the holes in the bottom then some the Drainage material, and then the soil. this will prevent the soil from being bogged up and marshy. the drains in the bottom will de a big help in getting the water out of the tank but without a drainage layer to keep the substrate from being too wet your plant roots could start to rot and your plants will die and smell. I would suggest a drainage layer for long term health. and nows the time to do it before you get the animals.
