I plan to purchase a needle nose gar (freshwater garfish, Xenentodon cancila (not a true gar)) for my 130 gallon tank. I read that these fish should have a planted aquarium, but I have a destructive oscar so he doesn't really allow me to have live plants. I do plan to get a few large floating plants, but other then that I can't have anything else. So my question is to needle nose gars absolutely need a planted aquarium or would they be fine without them?
