Description : I have a pond in the garden about 3 meters in diameter, 2 meters deep. Can any fish survive in it? Some for decoration. However, it does not have its own (electronic) pond. Will there be anything for me to live there?
Last Answer : You will find a lot of links on the net. For example here http://prima-receptar.cz/okrasne-ryby-do-jezirka/ Cannot answer unequivocally. If the pond has at least some inflow or water exchange, aeration may not be necessary. If it's just a callow where nothing moves, then probably nothing,
