Thanks for the advice guys. I don't have any aquarium plants and really don't want to mess with the expensive ones, that I don't like anyway, from the local pet stores. I guess my experiment will be plantless. The 20 gallon tank is setup and ready for the new arrivals for when they come this week. I will try maple leaves as forage (presoaked to remove the tannins smile ). I also have a 5.5 I'm not using. I think I will set that up differently tomorrow as Plan B and feed with scrap vegetables from the kitchen. I will post pics of both tanks once populated.
