thanks, everyone. The silver is in with the 2 pikes, marbled goby, 4 6" bichirs, 10" BGK and 3" gold saum. The jar is in with 5 10-12" bichirs, 13" FL/spotted gar, 3 6-8" dats and 10" LSN.
So far, the jar has only killed congo tetras and that was 6 months ago probably. It beat up the saum and started on the pikes when it was in the 125 (did not have the silver at the time), so I put it in the 210. So far, it hasn't really messed anything up. It will go after a couple of the fish from time to time but never strike it.
