is the pond heavily planted? if not chances are the eggs are all gone by now. and if it is then i would just leave it and ur find ur self with little more fish in a month time.
if ur serious about breeding then use the method above on my previous post. otherwise i would not bother doing anything at all as the fish will mostly be nymphs, comets or brown shrubs. invest in some more plants for the pond and u'll find ur self with more fish than u can handle.
