For starters I'd say your opening line is a bit rude and a little flawed. In your thread you claim to have gotten the firemouth last Friday, the 20th. So that's far from having them for a while. In fact hardly any amount of time to determine if any aggressiveness exists. As for doing "tests" on species compatibility, just wrong with the amount of resources available today. As well as experience. Whether they test water or not before a sale, is really nothing to go on. Your tank has been thru many ups and downs (more downs) and if he was that much of a friend and the store was that great, they wouldn't be selling you fish that are 1.) non compatible and
2.) not suitable for your tank size.
