I have a new container pond in a galvanized bucket that I put together about two weeks ago. Yesterday I noticed things swimming around. After investigating found out they are goldfish fry. My question is how did they get there? Did the eggs come in the new plant that I bought and put in the water? That is the only thing I can think of? It has Papyrus, water Hyacinth, and a pot that had a start from last year. The Papyrus and Hyacinth are the two that I bought. So now what should I do with them? It has an air bubbler in it and thats all. Also has some duckweed that come in the pot with the Papyrus.
