It's not uncommon for the stresses of capture and shipment to kill a fish within the first couple weeks. If you can quarantine your new fish alone for 4 weeks in a hypo salinity environment it will be a great way to get the fish in tip top shape before adding him to a busy tank. Just remember to drip acclimate him over a couple hours before adding him to the DT. As for the fish that died after 2 months it's hard to say.
