1. Some aros are pickier than others, silvers are especially known to be picky, not much surprise here.snyder810;2758107; said:wow, i'd say that is one bad off aro, i rescued two 3inchers from where i work that had ich, fins all torn up, and one even has a majorly malfunctioned spine. and they still ate the same day i put them in my tank. (crickets, freeze dried bloodworms, frozen krill, and have even taken a liking to small pieces of nightcrawler)
and unless that tank is heavily planted i'm going to go out on a limb and say there's no way you're at 0 of everything. (unless it's a very large tank with one or two fish).
