My mum has a fairly large garden pond which is stocked with several goldfish. They have been in the pond for at least 10 years. My stepfather always looked after the pond/fish and was very knowledgable. However, sadly he died last September so mum and I are trying to carry on his hobby and look after the fish.
We didn't feed them through the winter months, as per SF's routine. Started to feed them about 6 weeks ago and they were all happily coming to the surface and taking the food. But then one day 2 or 3 weeks ago they stopped coming to the top and we haven't seen sight of any of them.
Is this normal? Could it be the weather conditions aren't right for them yet and they're staying in the deeper water? Are they staying down to spawn? There's a net over the water so they can't have been taken by a heron.
We are mystified. Does anyone have any idea why they aren't coming up?Thanks in advance.
