Sorry for the frog's death . Myself recommend using tap water with a good dechlorinator like Seachem Prime. At least that way I know water is safe for frog. Bottled water could be anything and many are just filtered tap, some with extra chloramines. In the other side of spectrum you can have over filtered spring water that like R/O or distilled is bad for frogs. This article has more information on bottled water: http://www.frogforum.net/vivarium-te...hing-else.html.

A simple Frog First Aid Kit can be built using a few items: Pedialyte (or local equivalent); Honey (couple drops in a bath help out with constipation); a plain (no painkillers) topical antibiotic like Neosporin Original or Silver based type; some Q-tips; and finally a mild (Melafix) and stronger (Maracyn Plus) antibiotic if frog is aquatic, can go long ways to help until frog gets better or a visit to Veterinary is available. There are stronger meds some members keep; but their use need veterinary supervision and are $$$.

If you think about replacing frog, please read this first and follow it's advice: http://www.frogforum.net/general-dis...uarantine.html and http://www.frogforum.net/general-dis...ing-frogs.html. Thank you !
