1) temp was kept in the high 60's low 70's
2)diet : crickets earth worms and small gold fish (i think they were called comets)
3)it had probably been an adult for about three years (my best guess)
4) i ordered it from a petstore so i dont know about wild or captive bred.
5)the substrate was called jungle mix and it said it was good for all amphibians.

so i guess the only conclusion i can come to is that the cause of death was stress.
Bummer.
