Bought 4 goldfish and 2 bunches of Elodea about 6 years ago, for a small front hard pond. The pond now has about 20- 30 goldfish of various ages, including three originals (one jumped out whilst spawning and was discovered too late). The elodea has now populated two other smaller ponds as well as having to be “weeded” from the main pond three times a year. Very good value for money!
