Trying to harvest some mulberry leaves for my shrimp. I live in Southern Ontario, and I'm still unsure as to what kinds of mulberry grow here. I'm seeing a lot of information about red mulberry and how it's kind of endangered but not much else. What kinds of mulberry are safe for aquarium use? What kinds can be found in Canada? Is there any kind of prep work that needs doing before adding to the aquarium apart from boiling? If you recommend againtst harvesting, where can I purchase them for cheap? All info appreciated!
