How do i keep my fish from eating the plants in the pond? I used to have beautiful Patio Joes in the pond. Unfortunately the last cleaning guy killed them all. Fish never touched them. Can not find any Patio Joes here in Texas anymore, so I tried some other plants, extra hardy or tougher leaves...........within a week the fish eat them all. Tried a net, looks ugly........any ideas? And yes they are fed regularly and enough. Fired the cleaning guy, do it myself these days since I retired. Any help or suggestions are appreciated!
