My goldfish are spawning today, I noticed there are lots of little eggs around the edge of the pond and attached to various plant life. A lot is attached to some green algae that grows on the side of the pond.
Whats the best way to protect the eggs, I've always just left them to there business in the past but I have never seen and baby fish, so I presumed they just got eaten by the bigger fish or frogs.
I can't see a way of removing the eggs carefully so should I just make some sort of caged in section where the majority of the eggs are.
I have another question as well, I need to replace the filter sponges in the filter box, but I was just wondering about the bio balls at the bottom of the filter box, Im not sure if I have too many of them, reason being is the water at the top is level with the overflow outlet and sometimes the water escapes via the overflow outlet if the sponges haven't been cleaned for a week or two.
The top filter sponge is about 2-3cm from the overflow outlet.
I'm guessing I should remove some bio balls so that the sponges sit lower down, I do seem to have a lot of the plastic bio balls in the filter box they perhaps take up about half of the box.
Thanks
