I recently picked up a Mormyrus Rume from a seller on aquabid who I won't name (PM if you want to know who to avoid) who shipped it terribly. It arrived leaky and cold and with ich, barely ate if it ate at all (was hard to tell), and died within a week. Tried feeding it bloodworms, small live earthworms, frozen brine shrimp, krill, and even tried putting a couple of minnows in its quarantine although I couldn't figure out how it'd get them into its snoot. Was very very sad, as it was a cool fish I was really excited for.
