We have 3 ball pythons: two are 2 years old and one is 4 years old. We typically feed them once every four weeks. This past Sunday they were fed on schedule. On Monday, we found one two year old and the four year old dead in the aquarium along with one half digested mouse. When we picked the two dead ones up to clean out the aquarium, fluid poured out of the pythons mouths and nostrils. Also, we noticed that their undersides were pigmented a dark color that was never there before, that resembled a bursting of internal organs from the inside. The question we have is how could this have happened to two out of three ball pythons (who are all housed in the same aquarium)????? And also, how can we prevent the same unsavory outcome for the only surviving python????

Extremly confused and upset
