1.The frog may have been in poor shape before you acquired it and the transfer from store to home was just too much stress for it.
2. There may be something in your enclosure that killed it. Examples include untreated water (unlikely though)and chemical residues from cleaning products. Cage furniture that may have chemicals in it or on it is possible. I had artificial silk plants in an enclosure and lost two of three frogs within a few days of acquisition. I removed them and the third frog thrived.
3. Some unknown cause that may never be known. Frogs are delicate and sometimes some unknown factor causes their sudden demise.
Dont get discouraged. Odds are the frog probably had underlying health issues before entering your care given it only lasted a day. Did you examine the body? We’re there any signs of infection such as sores or reddening on the legs and belly? What conditions were present in the store you purchased it from? Was it wild caught or captive bred?
