Well done jacksparrow! Aren't they fascinating to watch? We have goldfish that breed every year and hundreds have survived. We've ended up with an indoor tank (for fry) and four ponds! Many have been given away. I have found that doing nothing is the best course of action. If conditions are ideal for them to breed, then they will be ideal for the fry to thrive, so I just try to maintain water quality and leave them to it.
