I know that Uaru's are notorious plant eaters, but is there ANY way possible to keep them in a planted tank? I have three 4" long uaru's in a 70 gallon tank, and would love to convert it to a plant tank, but I LOVE my uaru's and don't want to get rid of them. Would certain plants be less appetizing to them? No, I don't have another tank to move them into. Is this just a hopeless fantasy? Thanks, Dan
