Hi guys, thought I'd update you on the state of our ponds! It's been a while and the system is now up and running, pond life included. The largest pond (the fish pond) has now got fish, 17 goldfish (all about 2 inches long) and 4 grass carp (which I've read are not suitable for the pond, but they're in there so I'm not sure what I can do about it now). We had frogs spawn in both the fish pond and the splash pool, and there are now froglets everywhere, which is awesome. There are 2 water lilies in the fish pond and 1 in the splash pool, plus some blanket weed and what looks like some elodia which came in with the lilies presumably. Yesterday while I was in the garden I noticed tiny fish in the pond, and caught a few. Looks like the goldfish have been breeding? I was told that technically our pond was already overstocked, but they are breeding, what do I do?
