erm not a question I think that has been asked before - but actually quite a good idea in a way.
Severums will always eat plants which is annoying but your kind of right if you could do something with a kind of caging it might work but you have to be clever with how you did it so that the fish still had plenty of room.
There are some metals that are fish safe but not sure what the effects are from it over a long time - same with plastics really. You could use twigs from some types of wood that might work?
