I have 3 silvers and 2 jardinis from the same batch, my smaller jardini is by far the meanest, the bigger one get's along perfect with the silvers... at least for now.
had to remove the temensis because it was stressing the aros, now this sounds strange, but the only fish my mean jardini is affraid of is the flagtail, lol
for now they are in a 1100 liter tank, 2 jars 4", 2 silvers 5", 1 flagtail 5", 1 pleco 8", 3 chitalas 5", 1 mbu puffer 5" and a blue peruense gobby. it all still looks pretty calm
