What are your water parameters?

Never add any new fish to an aquarium that has had fish die in it recently. The remaining fish must be healthy and disease free for at least 1 month before adding new fish.

All new fish, shrimp, plants and other life forms going into an aquarium should be quarantined for 2-4 (preferably 4) weeks before being added to the main display tanks.

These words are utterly golden. Unfortunately I often take risks. Sometimes they pay off when I'm sure I know what caused the fish to die but sometimes I'm wrong. Best to do exactly as Collin says.
