LFS had a beautiful 4" jardini in with some parrots and florida gars. Employee says no problem, but of course he would. I have a big tank, with 3 gars, 2 dats, and a few bottom dwellers. Do you guys think I could achieve harmony with a jardini or should I just get a silver?? I love my tropical gars and don't want anything that will kill them but they don't really movce much for a rival!!??
