I had to move my Java Fern. The Uaru didn't bother it as long as I had valisneria or some cryptocornes in the tank. Once they finished those off they started to mess with it. The only thing they haven't bothered are my Anubias plants. I thought about getting some duckweed to float for them since it grows pretty quick it may be able to outgrow their appetite.
you would have to add stupid amounts of duckweed to beat their appetites. i added loads and i didnt have any left after an hour then they went back to my elodea. the elodea keeps them off java fern and my anubias nana. but i have to replace the elodea after one or 2 months with new bunches because even that cant grow fast enough to beat them.
interesting. suppose it will depend on the fish like with cichlids attitudes. try any plants then mate. trial and error seems the way to go. good luck.
