  • Question
    Can I use any plant instead of lettuce?

    Yes, you can use almost any plant leaves that are not poisonous. For example, grass, tree leaves, and cucumber skin.
  • Question
    What's the other alternative of algae water?
    Community Answer
    You can buy Copepod cultures at your LFS or online. Almost the same process, but you'll want to maintain your culture with aged aquarium water (after a water change) or rain water. Put the container you chose to use under direct light for 48-72 hours for bacteria and phytoplankton to grow for copepods to eat and you're set. Or, if you have a spacious, well-off tank, your fry can survive off of the ecosystem of the tank. I've left fry in the same tank as they were born, yes a couple were eaten, and they've grown into full adults in a 10 gallon tank.

    In making infusoria, should the bottle filled with lettuce and water be closed, or left open for several weeks?

    Use a third of the jar filled with lettuce, then keep the lid open. An open lid helps circulate the oxygen from the air, and if you set the culture inside then stir once/twice a day just to keep it saturated.
