This is the second time this has happened. I have a galvanized wash tub container pond, I have just two plants in it that I wintered over a papyrus and some grass. I put some water hyacinth in the tub when those came in and now I have three babies swimming around. I think the eggs must have been on the hyacinth. Cause the other two plants haven't seen fish since last summer. The pond has no aeration or pump. What do I need to do to ensure the babies growth? I would like to see them survive, they look multi colored. I put flake food every once in a while but not sure if they know what that is yet.
