My three year old pond is thick with lilys whose leaves have a lot of

goldfish & catfish. Thanks for any suggestions.

Most likely aphids. Rinse them off regularly. The fish _may_ eat them
(always worked for me, often doesn't for others - I'll never understand
fish :-) ). If the fish don't, at least the aphids aren't going to like
it.
