The spouse's tank will finally be stocked and ready to go to his work office this weekend. It's been on the coffee table in our living room...going to miss having a tank there so I've been looking at either a Fluval Spec 5 or Eheim Nano 6g. No definite plans for the tank. Both get good reviews so I was wondering if there are any pros or cons to either, or which is a better all around tank.
