You live in Scotland (big smile!)
I lived in British Columbia most of my
childhood and have found memories of
Scottish incomers and probably the same
kind of weather.

Goldfish will eat their own eggs, the little pigges. Have you ever noticed them
spawning?
They will chase each other around and the males will knock against the females
when they get them cornered.
To save the eggs - they like to deposit them on floating vegetation. Some folks
used commercially available spawning mats - kind of like string mop heads
(which probably work too).
The eggs are visible to the eye. You can remove the mat to a stock tank or
aquarium. (others can provide more detailed information about rearing)

Spawning is triggered by warmth of the water,
new water, full moon(?)


kathy :-)
