Very sorry your toad died . Please read this article that will help you understand toads needs in captivity: Frog Forum - Toad Basics - Keeping ground-dwelling Toads. A care sheet for Bufo, Anaxyrus, Spea, Scaphiopus, Ollotis, Alytes, Pelobates. Water should be treated tap, usually recommend Seachem Prime or ExoTerra Aquatize. Bottled water can be anything since they are made to meet city/state codes, even so called "Spring Water" is treated: http://www.frogforum.net/vivarium-te...hing-else.html. You should clean (rinse in hot water) and refill it's water dish daily, even if it looks clear.

Frogs and toads in captivity need food supplements, more info on that in here: http://www.frogforum.net/food-feeder...schedules.html. A diet based on Canadian night crawlers (not dyed from local bait shop) is OK. Can cut the worms from pointy end for smaller toads. Feeder crickets should be sized same or smaller than distance between toads eyes and gut loaded 24-48 hours with lettuce, carrots and cherios cereal before feeding toad.

Wild caught animals usually cary a load of parasites and other pathogens that need to be checked for and if found, treated. That can be very costly and one of the reasons we recommend a captive bred animal, specially for beginners. Hope this helps you care for any future toad pets, good luck !
