There is a chance I may be allowed to build a pond at the house we may be moving to, but this is all just the information gathering stage. If we move, I'll be cutting down on Betta tanks to two or three instead of five, so my mum said a pond would be nice and I might be allowed to build one. I would be putting goldfish in this pond, and I just need to ask some questions to all goldfish lovers.
The woman at the stores said for goldfish to remain in the pond over winter, it must be 3ft deep. But she also said it would be 15 square feet, the one I was thinking of doing.
How many goldfish can the pond said above hold?
Is this information correct, that the goldfish can survive over the winter in that deep of a pond?
If not, how deep must it be?
Can I combine Shubunkins and Comets in a pond?
The woman said that if I put in a lot of plants and an aerator and clean it yearly, a filter is unnecessary. Is she correct?
If everything she had told me is wrong, what plan of action do you suggest I take?
Thanks to all who answer!
